I updated to latest RStudio (RStudio-2023.03.0-386.exe) but R would not run. Error message: Error Starting R The R session failed to start. RSTUDIO VERSION RStudio 2023.03.0+386 "Cherry Blossom " (3c53477a, 2023-03-09) for Windows [No error available] I also tried RStudio 2022.12.0+353 --- same problem. I then tried another older version of RStudio (not sure version as I changed file name by accident) and R ran. Any clues? Please help. Thanks.
p.s. But now I click some (but not all)? .R file and cannot see the source code. On 4/6/2023 5:28 PM, Steven T.

No, but you need to ask on an RStudio mailing list. This one is about R. Best, Uwe Ligges On 06.04.2023 11:28, Steven T.

RStudio is its own project, and they have shifted their emphasis somewhat regarding R somewhat. The web site now states that the organization - now called Posit - is not de-emphasizing R so much as extending to empbrase Python. The current version of RStudio requires R 3.3.0 or later.
