Is there a way to load different versions of R, in windows.
Yes, on Windows each R version gets installed independently. Can you please clarify what is your specific problem with this?
I use a combination of RStudio and Rattle to help friends learn R. Rattle uses a RGTK2 package, which Cran no longer supports and comes up with a UTC or something like that error.
We have found that by using R4.1 and Rstudio 22.02 we can get Rattle to work, etc.
It would be nice to use a more later version of RStudio with the earlier version of R. But some times I need an earlier version of R and other times a Later version of R.
Hence, my question about getting RStudio to pick which version of R i want to use.
Well, you haven't mentioned RStudio in your original question.
The open source version of the IDE doesn't support quick change among R versions but you can choose the R version on startup by holding the Ctrl key while opening RStudio, then you should see this menu and you can choose the desired R version.
Another option is to use rig
thank you for this information. It has been very helpful.
