Switching to a Newer Version of R in IDAS

If you want to switch to using a newer version of R in IDAS for the first time, for example, from R 4.1 to R 4.2, you will need to:

1. Double check and set your user library path using .libPaths() in R.  For more details, please see the section Setting (Changing) the User Library Path below. 

2. After you have done step 1 above, you will need to reinstall any R packages that you need for each version of R that you use. After you have set the user library path as in step 1 above, you can install packages with install.packages() in R as usual.
