Checking in with R-Ladies Taipei

By Blog, Events
 Kristen Chan, R-Ladies Taipei organizer

R Consortium’s R User Group and Small Conference Support Program (RUGS) is made to support R groups around the world by providing grants to help R groups organize, share information and support each other. Unlike many groups over this past year, the R groups in Taiwan did not have as long a disruption as other groups did. Can they provide a glimpse of how the rest of the world can hold regular meetings? Do they have a way to mix the wave of virtual meetings along with local meetings? We talked with Kristen Chan, current R-Ladies Taipei organizer, to find out more.

RC: What is the R community like in Taiwan?

In Taiwan, we have two R communities, one is R-Ladies Taipei which I host, and another one is Taiwan R user group. Both of the R communities promote and build up venues for friendly data discussion. We welcome talks on any data topics such as Machine Learning, Deep Learning, Data Analytics, Data Engineering, and meet every Monday night. The last Monday of every month is reserved for women.

RC: In the past year, did you have to change your techniques to connect and collaborate with members?  

In Taiwan, at the very beginning of 2020, we stopped the face-to-face meetup and started thinking about how we can continue to maintain the meetup. But how lucky we are! Taiwan’s CDC has the pandemic under control, so we can do everything as normal. So we still have the regular meetup, but we require everyone to wear masks to protect each other during the event.

RC: Can you tell us about one recent presentation or speaker that was especially interesting and what was the topic and why was it so interesting? 

In October 2020 we held a satRday conference. It was the first time we had this satRday event and also it is the first one in Asia. And it was tough to make this conference happen during the COVID-19 pandemic. Fortunately, we had invited Yihui Xie who works for RStudio to give us a wonderful talk. We are using the online meeting to make this happen. The topic is R Markdown. It was an interesting and unforgettable presentation because most of us don’t have the experience to talk to the author directly, so all the attendances were learned a lot.

RC: Do you know of any data journalism efforts by your members? If not, are there particular data journalism projects that you’ve seen in the last year that you feel had a positive impact on society?

Yes, some of our members are reporters. They are learning R and some BI tools to help them deal with the data cleaning and make some graphs to let people know more about information. 

And we also have a community called “知了新聞 Cicadata.” It’s a community about data journalism and its goal is that they want the data journalism field more open. By the way, one of the founders of 知了新聞 is also Taiwan R user group’s current organizer.

RC: When is your next event? Please give details!

We are still planning the event. But I think we will have a series of beginner  tutorialmeetups to let more people know R.

RC: Of the Funded Projects by the R Consortium, do you have a favorite project? Why is it your favorite?

My favorite project is “Consolidating R-Ladies Global organizational guidance and wisdom”. Because of the diversity issue, it touched me more. 

RC: Of the Active Working Groups, which is your favorite? Why is it your favorite?

My favorite is “Distributed Computing.” Because the data becomes bigger and we need to deal with that and also want to save some time, what we need is Distributed Computing.

Spectacularly Prescient – satRday South Africa Covered COVID Data Before Pandemic Hit

By Blog, Events

R Consortium’s R User Group and Small Conference Support Program (RUGS) provides grants to help R groups around the world organize, share information and support each other. The wealth of knowledge in the community and the drive to learn and improve is inspiring. With the wide disruption of events due to COVID-19 this year, we are interested in how groups are getting on despite the disruption in normal communication. The pandemic has focused our interest to look at how we communicate both at conferences as well as communicating with people outside of the main events while navigating the new challenges that the pandemic has created.

We talked with Andrew Collier, Data Scientist, Fathom Data, and satRday conference organizer, to find out how the R community in South Africa is faring. 

RC: How has COVID affected your ability to connect with members?

Well, we have run our conference for four years in succession. Actually, in 2020 we had the conference on the day that they announced the first official COVID case in South Africa. It was an in-person conference, but basically it was immediately before lockdown. That’s completely derailed our plans to do anything this year. I don’t really think I have the appetite for organizing an online conference. If I’m going to organize a conference I want to see people in the flesh.

That’s on the conference side, but as far as the meetups are concerned they are still soldiering on. Actually, I gave a talk for R-Ladies Cape Town towards the end of last year and they are still holding fairly regular meetings. It doesn’t seem to have a massive impact on them. If anything, I suspect that they are finding the logistics of organizing the meetings easier because they don’t have to organize a venue or eats or that kind of thing.

RC: How did the technology to connect change over the last year?

It varies. I know that we did the talks to R-Ladies Cape Town on Google Meet. But, I’ve also seen them using Zoom, and I’ve also seen them using Microsoft Teams as well. All kinds of platforms.

RC: Can you tell us about one recent presentation or speaker that was especially interesting and what was the topic and why was it so interesting? 

If I could pick out a talk I really enjoyed, and was spectacularly prescient at the time, it would be a talk at satRday last year where Robert Bennetto told us about COVID and what was going to happen before it happened!. So he had done a bunch of modeling, and everyone else was thinking “Hum, what’s the COVID thing all about,” and he stood up on stage and told us and within days what we had been told at the conference was our new reality. People didn’t see the relevance at the time, and they didn’t realize the enormity of what was about to happen.

RC: Do you know of any data journalism efforts by your members?  If not, are there particular data journalism projects that you’ve seen in the last year that you feel had a positive impact on society?

I’m not aware of anyone who has been to the conference who is a data journalist. I have a couple of contacts in Cape Town who are data journalists but they don’t use R as their main platform. The other thing that I have seen a lot of journalists do is that they go so far in R but then they take it across to another tool … to tweak the presentation. Like take it across into inkscape, and then actually build the visualization in inkscape, which to my mind kinda defeats the object of having a reproducible system if component of it has to be done by hand.

RC: When is your next event? Please give details!

We don’t have any immediate plans. I don’t think we are doing it this year. February, March, April worked out to be a good time relative to school terms and public holidays and things. It was a time where we could find a weekend when most people didn’t have any commitments. And the rest of the year that tended to be tricky. If it was to happen again it would be the same time next year.

RC: On social distancing on possible future events

I would prefer not to do that, but I think that realistically we would have to. Unfortunately it does make social interactions more difficult.

RC: Of the Active Working Groups, which is your favorite?  Why is it your favorite?

The R-Ladies group is my favorite, and I am a little bit awed by how successful that group is. I have tried to run meetups myself, and it’s hard work. And it’s not particularly rewarding because at least where I live people will sign up for a meeting, and say I’m coming and on paper you’ll have 50 people coming to your meeting, and you’ll arrive having catered and only a few people arrive. I’m not exaggerating, that’s a realistic scenario. So, that’s a little bit disheartening. But the R-Ladies are well attended so, I don’t know what the secret sauce is, but it does work.

Find out about the R Community in Zurich, Switzerland

By Blog, Events

R Consortium’s R User Group and Small Conference Support Program (RUGS) provides grants to help R groups around the world organize, share information and support each other. The wealth of knowledge in the community and the drive to learn and improve is inspiring. We had a chance to talk with Muriel Buri, Statistical Scientist and organizer of Zurich R User Meetup, to find out more about the R community in Zurich, how they’re holding up during the pandemic, trends in R, and what the future holds. 

If you are interested in applying to the RUGS program for your organization, see the How do I Join? section at the end of this article.

RC: What is the R Community like in Zurich?

We started with the RUG in 2015 and by now we have just 2000 members. However, looking at Switzerland, there are smaller communities based in Lucerne and Bern and there is one R-Ladies group in Lausanne, which’s the French part of Switzerland. They all are a bit smaller, however, it’s a nice exchange between the groups and as you might be aware, the Zurich team is very much involved in organizing the Global User R Conference.

Zooming back in on the R community in Zurich, it’s a very diverse community. As mentioned, the Zurich RUG was founded in December 2015 and has been growing substantially since. The frequently organized Meetup events regularly gather a crowd of over 100 people and foster a very lively and intensive exchange among the R community in the Zurich region. The diversity regarding the applications of R, as well as the different occupations of the useRs in the community, such as data journalism, academic research, different insurances, official statistics, foundations, etc. are unique and outstanding characteristics of the Zurich R community.

The diversity is also what I enjoy the most at all these meetings. Not just having an exchange between the group you usually interact with, but having a broader exchange with different people, professions, levels of useRs, application fields, etc. To summarize, the community is very inclusive, and there is no such thing like a stupid question.

RC: How has COVID affected your ability to connect with members?

The Zurich RUG has shifted its focus a bit as many of the RUG members are now actively involved in the virtual global useR! 2021 conference. This has already started when we originally applied for the (planned) in-person useR! 2021 which has by now became the global virtual useR! 2021 conference. Hence, for me, it is challenging to distinguish between how COVID has affected us and how our engagement in the organisation of the useR! 2021 has affected our local activities.

At the start of the pandemic, we did not organise anything. After two or three months into the ‘lockdown’ (which in Switzerland was quite soft in comparison to other countries), the small group of the RUG Zurich organizers met in a park for lunch. At that time, I do recall that we all were a bit Zoom-fatigued. We then waited for a while and organised our first virtual event in October 2020. It was nice and many people attended it. However, what we always enjoyed best was having the beer part afterwards. Having this all virtual just wasn’t the same. It is very difficult to get that socializing part going in a virtual space.

Luckily, the Swiss R community is still active thanks to the Lucerne useR! group (@lucerne_r) which have actually started during the pandemic. They nicely promote their online events on Twitter, and we’d always retweet these tweets for our own community. It is nice to see that the community isn’t asleep.

RC: Can virtual technologies be used to make us more inclusive?

I personally do believe that virtual technologies do have the power to make us more inclusive, yes. As an example, the useR! 2021 conference will be the first R conference that is global by design, both in audience and leadership. Leveraging a diversity of experiences and backgrounds helps us to make the conference accessible and inclusive in as many ways as possible and to grow the global community of R users giving new talents access to this amazing ecosystem. New technologies make the conference more accessible to minoritized individuals and we strive to leverage that potential. Additionally, we pay special attention to the needs of people with a disability to ensure that they can attend and contribute to the conference as conveniently as possible. 

That being said, we will surely do our best to use these innovations also later within our own Zurich based community.

RC: Can you tell us about one recent presentation or speaker that was especially interesting and what was the topic and why was it so interesting? 

There is no specific presentation that I would like to highlight. To me it seems our audience always appreciates events with learning tutorials very much.


For example, we once had a presentation on Docker for R users. Another time, we were able to encourage Martin Mächler to give a talk. That was also really great. His presentation was entitled “What I find important in R programming and recent cool features in R.”

The way we often organize our meetups is that we will have one specific topic and two speakers presenting. As mentioned, the R community in Zurich is very heterogeneous so that we would for example have a financial theme for one meetup and would then look for a bank to sponsor and/or host our event. Or we’d have an insurance related topic and try to organise this event at an insurance company.

RC: What trends do you see in R language affecting your organization over the next year?

In the age of this pandemic, virtual meetups have become an indispensable tool for the community. Based on this, I was wondering if the local R community groups will still be as important as they used to be. It seems to me that the community is moving closer globally and even more (virtual) exchange is happening. 

The question of predicting a specific trend in R language affecting our organization over the next year is challenging. From my personal perspective, as I now work in the pharma industry, I see a big trend moving away from SAS towards R. With this, the promotion of friendly end-user Shiny Apps to present and discuss data analyses to people who are less familiar with the concepts is a big trend too.

RC: Do you know of any data journalism efforts by your members? If not, are there particular data journalism projects that you’ve seen in the last year that you feel had a positive impact on society?

Yes, indeed, there are at least two members at Zurich RUG, Timo Grossenbacher (@grssnbchr) and Marie-José Kolly (@mjKolly). They have both presented their work at our meetups and the community has been very interested in their talks.

Marie-José writes data journalism articles for the Republik magazine in Zurich. One of her articles is about the protection of unborn life and the woman’s right to self-determination. The article allows for a visual journey through the weeks of pregnancy. The article is also nominated for the Swiss Press Award and can be accessed here (paywall, in German).

RC: Of the funded projects on R Consortium, what is your favorite project and why?

To be honest, I wasn’t aware that there are so many different funded projects on R Consortium. What a great effort!

The satRday conferences are events that I enjoy very much. The support of the R-Ladies groups is surely also a project that I personally like a lot.

RC: There are four projects that are R Consortium Top-Level Projects. If you could add another project to this list for guaranteed funding for 3 years and a voting seat on the ISC, which project would you add?

That is a challenging question. I worked myself in Uganda and taught statistics to veterinary medical doctors. R as an open-source program for statistical computing is fantastic as everyone with internet access can make use of it. I think I would personally promote more such projects to promote the growth of the global community of R users by advancing its accessible and inclusiveness. I’d initiate a project that promotes the global use of R. This vision is motivated by my experience of seeking sponsors for the global useR! 2021 conference. We did experience some challenges to gain access to all global communities, e.g. R is used in so many parts of the world but not everyone yet might be aware of the great resources, the worldwide community and the global exchange… Yes, I would suggest a project that pursues this vision.

Upcoming Event: The role of data journalism in the COVID-19 pandemic

By Blog, Events

Join us March 18, 9:00 a.m. – 10:30 a.m. PDT. More information!

The role of data journalists in the scientific process has traditionally been overlooked. However, the most recent pandemic showed how journalism shapes scientific responses and public policy. Thousands of journalists rose to the challenge when the public needed information in order to respond to the rapidly spreading COVID-19 pandemic. Journalists acquired COVID-19 data, visualized it and disseminated their work to help the world contain the virus and flatten the curve. 

In order to effectively respond to the pandemic, the world needs a coordinated response driven by accurate, complete data. The data must encompass local outbreaks and be released quickly so action can be taken. Journalists, with experience collecting local information and releasing articles in a timely manner, were well suited to help inform the public. However, by visualizing and analyzing COVID data, journalists became participants in the scientific process rather than simple conveyors of results. Their efforts help data scientists, inform decision-makers and shape a new role for data journalism in crisis situations. 

On March 18 the COVID-19 Data Forum, sponsored by the Stanford Data Science Initiative and R Consortium, will host a meeting to discuss how a new breed of data journalists collected quantitative data that helped fight the pandemic. The forum will also discuss how data scientists utilize their resources to create better models. 

Speakers: 

The event is free and open to the public!

Beyond Case Counts: Making COVID-19 Clinical Data Available and Useful – Aug 13, 2020

By Blog, Events

Thurs, August 13th, 9am PDT/12pm EDT/18:00 CEST – Register now!

Hosted by the COVID-19 Data Forum/Stanford Data Science Initiative/R Consortium

COVID-19 is the first pandemic to occur in the age of open data. Public health agencies around the world are releasing case counts to the public, and scientists are providing analyses and forecasts in real-time. However, the content of this data has so far been limited to simple metrics like cases, deaths, and hospitalizations at coarse geographic and demographic scales. To drive the next phase of COVID-19, scientists need access to higher-dimensional patient-level data, so we can understand how the virus causes disease, why are some more at risk than others, when and how is transmission occurring, what therapeutics are more likely to work, and what healthcare resources are being used. But sharing such data brings up tremendous challenges in terms of patient privacy and data standardization. The COVID-19 Data Forum, a collaboration between Stanford University and the R Consortium, is hosting the event “Beyond case counts: Making COVID-19 clinical data available and useful” to push the conversation forward on these issues. The event will include talks by representatives from international collaborative teams who are working to collect and share detailed clinical and biological data from individuals with COVID-19. The event will be open to the public, and is part of a continuing series focusing on data-related aspects of the scientific response to the pandemic.


Speakers include:

  • Jenna Reps, Observational Health Data Sciences & Informatics (OHDSI) Consortium /Janssen R&D
  • Andrea Ganna, COVID-19 Host Genetics Initiative/Harvard Medical School/Finland Institute for Molecular Medicine
  • Ken Massey, EndPandemic National Data Consortium/Saama Technologies
  • Ryan Tibshirani, DELPHI epidemic forecasting group/Dept of Statistics, Carnegie Mellon University

XI Conference of R Users (Madrid, Spain, Nov 14-16) Welcomes Over 200 Attendees

By Blog, Events

Thank you to Carlos Ortega, Principal Data Scientist, Teradata, for providing this summary and pictures from the conference

The XI Conference of R Users (XI Jornadas de Usuarios de R), held November 14 – 16, Madrid, Spain, was organized by the Asociación Comunidad R Hispano. The ambitious program and the invited international speakers made the participation massive, exceeding 200 attendees. The Conference was divided into two locations, Repsol (Spanish Gas and Oil company) and UNED (Spanish Distance Learning University), highlighting the university-business combination that has been one of the key factors in the success of the conference.

On Thursday, November 14, the opening ceremony was held at the Repsol Campus auditorium and attended by Emilio López Cano (president of the Asociación Hispano R Community), Julio Gonzalo (deputy vice chancellor for research at UNED), Enrique Dameno (Director of Digitalization and Integrated Customer Management of Repsol), and Teresa García (Repsol).

Max Kuhn (R Studio) gave a lecture on “Modeling in the Tidyverse,” and after that, in the round table “R in business,” the crucial role of data scientists in solving problems in diverse areas was covered. Raúl Vaquerizo (Pont Group), Noelia Ruiz (Mutua Madrileña), Jorge Ayuso (Telefónica España), Enrique Lasso (Repsol) and Carlos Ortega (Teradata) participated in the round table.

On the 15th and 16th, at the School of Education of the UNED, an extensive and vibrant program was developed with workshops, communications sessions, “lightning sessions,” poster sessions, round tables and invited conferences. Bernd Bischl (University of Munich) gave a lecture on MLR3, Jo-Fai Chow (H2O.ai) presented “Automatic and explainable machine learning in R,” and Max Kuhn gave a workshop on “Designing R modeling packages.”

Following the multidisciplinary philosophy of using R to handle any kind of data, communications sessions dealt with applications in genetics, data analysis, model and project management, society and culture, surveys and education, medicine and veterinary and economics and company. In addition to these monographic sessions, the “lightning sessions” dealt with many different topics.

A round table on Data Journalism was held to close the conference, moderated by Leonardo Hansa (R-Hispano) in which Virginia Peón (Indigitall), Alba Martín (Newtral), Antonio Delgado (Datadista) and Carmen Aguilar (Sky News) participated. The importance of knowing how to treat the data in an appropriate and honest way was highlighted, so that information that reaches the public is truthful.

In the closing ceremony, the prize for the Best Young Work of the Conference was announced, which went to Rocío Aznar Gimeno (Technological Institute of Aragon) for the work “Multilevel mixed models: An application of the lme4 library to estimate the fetal weight percentile in twin pregnancies.”

Sessions Available

Many of the sessions were streamed and recorded. They are accessible through the UNED Channel (Canal UNED): https://canal.uned.es/series/5dc3f7d05578f252041fc22d

Interview R/Medicine 2018 conference organizer Micheal Kane

By Blog, Events

The first annual R/Medicine conference is being held September 7-8 in New Haven, CT, and is a collaboration between R Consortium and the Yale School of Public Health Biostatistics Department. As the first public activity of the R in Medicine working group, it’s set to be a key event to bring together the medical community that leverages R in medical research and clinical practice.

Leading the conference committee is Michael Kane, who is an Assistant Professor in Yale University’s Biostatistics Department. With the conference coming soon he agreed to answer a few questions about the R community and the conference itself.

Tell us about the medicine industry’s use of R?

Michael: My first exposure to medicine using R came from my internship at Revolution Computing (now Microsoft R). At the time most companies used SAS and Revolution had started providing validated versions of R and some packages, similar to SAS’s validation process, which would allow R to be used in submissions to the FDA. Since then, the rules have changed, and R sees a lot more use in this space because it provides inexpensive access to powerful tools for designing and analyzing health, genetic, and clinical data. 
We are currently using and developing these tools to find subtypes in immunotherapy studies for treating cancer. Patients can respond very differently to cancer therapies depending which stage of cancer they have, how many previous treatments they’ve had, and the diversity of the tumor environment. By understanding how factors like these are related to prognostic heterogeneity, we can do a better job prescribing people with cancer the most effective possible treatments.

What drove you to create an event to bring together the R medicine community?

Michael: This conference was inspired by R/Finance. The committee does a fantastic job of providing an entertaining and informative conference. The richness and diversity of the talk subjects show how vast finance is and, at the same time, the speakers and other attendees are completely accessible. We want to bring that same sense of inclusiveness and collaboration to medicine, where sometimes practices become siloed. We hope people realize that we, in medicine, are also part of a rich large and rich area of research and we hope the conference helps to jell the community.

What is the organizing committee’s goals and measures of success for this first event?

Michael: Our goal for the first year to better understand the community as a whole. We are expecting submissions from the clinical trials community, the genetics and omics community, and the epidemiology community. We are hoping we get submissions from both academia and industry. We want to see how people are using R to advance human health. I’ll consider the conference a success if attendees find at least one talk where they are surprised, entertained, and delighted by a use of R that hadn’t occurred to them.
Our other goal is to reinvest in the conference. If we are successful, and we are able to secure enough sponsorship, then we would like to make it easier for people to attend the conference. This would include providing more awards for travel, particularly for students.

How do you see working with R Consortium as critical for driving consensus and critical mass in the medicine community?

Michael: The R Consortium has become the umbrella for the entire R community. Their approval lets the community know that this is the conference to go to if you are using R in Medicine.
We thank Micheal for his time, and hope that if you are in the medical community using R that you look to attend this event.
