Using R with ArcGIS

With a successful collaboration between DSSC and ESRI, a hands-on workshop on ESRI R plugin was presented by Shaun Walbridge, a senior developer from ESRI, on Wednesday, April 20. Shaun provided an in-depth tutorial on how to use R in ESRI, and answered questions from students and librarians.

Our audiences were from a broad background: librarians from Columbia and other institutions in NYC, PhD students, Master’s students, people from administrations, etc.
