I used rstudio a lot in my undergrad but haven't used it in a few years. I have tried downloading multiple versions of r and can't find one that is working for most of the packages I need ( tidyverse specifically ggplot2, janitor, skimr, tseries, forecast, summarytools, etc). My laptop is running macOS sequoia version 15.7.2 with an intel processor. Does anyone have suggestions for what version of r to be running? I'll also take any tips for getting everything up and running again.
I'm running R 4.5.1 with RStudio 2025.09.2+418 under Sequioa 15.7.2 on a Intel i7 MacBook Pro.
Make sure you download the R build for Intel macs. Otherwise what exactly do you mean by (not) "working"?
You can also try rig: GitHub - r-lib/rig: The R Installation Manager
rig will always install the right versions, lets you install multiple R versions and switch between them, etc.
