This article is originally published at https://rviews.rstudio.com/
R/Medicine 2021, the premier conference for the use of R in clinical applications is less than two weeks away! This conference reflects the increasing importance of data science, computational statistics and machine learning to clinical applications, and emphasizes the effectiveness of the R language as a vehicle for making data driven medicine accessible to clinicians with diverse backgrounds. The two conference keynote talks Bringing Machine Learning Models to the Bedside by Karandeep Singh and Dissecting Algorithmic Bias by Ziad Obermeyer directly address important technical and ethical issues confronting modern data driven medicine.
R/Medicine will offer six short courses spread out over the two days of August 24th and August 25th. These courses are included in the registration price. The Tuesday short courses will be:
- Secure Medical Data Collection: Best Practices with Excel, and Leveling Up to REDCap and collaboratoR taught by Peter Higgins, Will Beasley, Kenneth McLean
- Intro to R for Medical Data taught by Ted Laderas, Daniel Chen, Mara Alexeev
- An Introductory R Guide for Targeted Maximum Likelihood Estimation in Medical Research taught by Ehsan Karim
The Wednesday short courses will be:
- Mapping Spatial Health Data taught by Marynia Kolak
- Reproducible Research with R taught by Alison Hill and Stephan Kadauke
- From SAS to R taught by Joe Korszun
The conference will proper will run from 11:00 to 19:30 EDT on Thursday, August 26th, and from 10:50 to 18:00 EDT on Friday, August 27th. The full schedule is here. Priced at only $50 full fare, $25 for academics and $10 for students and trainees, this is an affordable, important conference that you will not want to miss.
You can register here.
To get an idea of the international scope of the conference, and a feel for what the virtual conference experience might be like, have a look at the R Journal article written by the organizing team about last year’s conference: R Medicine 2020: The Power of Going Virtual.
And finally, to get an idea of the various ways that R is contributing to getting everyday work done in clinical practice: the following are the packages from the Medicine category that made it to my lists of “Top 40” new CRAN packages in posts over the past twelve months.
