I am a recently-"minted" administrator for lab's Linux server, and am trying to upgrade our version of R to 3.6.2 while maintaining the old version (previously, our group would simply install the new version of R to the /usr/bin location). In addition, we have a functioning Rstudio Server, and I would like that to also utilize the new version of R. Ideally, the new version would be the default, but the old version would still be accessible.
To this point, I have tried several ideas from various blogs, especially on this website. Specifically, I have referred to this "https://support.rstudio.com/hc/en-us/articles/215488098". However, calling R and using Rstudio Server still refers to the old version because it still resides in /usr/bin/R.
Any thoughts or ideas would be appreciated!
