R Software Versioning

It’s essential we all operate on compatible software. Thus, we will move to one main R version, and 1 repository snapshot date. Both will be considered for update every 6 months. We will be using both rig (r-lib/rig: The R Installation Manager) and renv (https://rstudio.github.io/renv/) to support this.

NSWERS Systemwide R version

# If rig default does not work run this
# Replace X.X.X and path/to/Rscript with appropriate values
rig run --r-version X.X.X --script /path/to/Rscript
