I want to change my RStudio version to R 3.4.1 - packages used in one of the scripts don't work with the newest version (eg. "eurostat"). I have a prepared folder with RStudio version and on Windows I just go to Tools -> Global Options and change the RStudio version to the folder. On Ubuntu this option is missing!
How can I handle this issue? I'm not a computer expert, I've already tried going through this tutorial: https://support.rstudio.com/hc/en-us/articles/200486138-Changing-R-versions-for-RStudio-desktop . I typed the command
where I exchanged /usr/local/bin/R for a path to the folder with another RStudio version. Nothing has changed. What should I do?
