R graphics engine version 15 is not supported by this version of RStudio.

RStudio IDE

Warning message:
R graphics engine version 15 is not supported by this version of RStudio. 
The Plots tab will be disabled until a newer version of RStudio is installed.

This warning appeared today out of nowhere. The plot pane is indeed annoyingly disabled. I did not update anything so I don't know why it suddenly appeared.

I assume RStudio pushed an update which broke my installation. Unfortunately I work for an organisation which does not allow us to have admin rights and which is very slow to respond to software/update requests.

Is there another way to fix this aside for waiting several weeks for my organisation to update RStudio?

You are using a very old RStudio version so no update on their side has happened (besides they can't / don't have a reason to, do a remote update).

However you are using the latest and greatest R version which has a new graphics engine that is not compatible with old RStudio versions, so this update (which has nothing to do with RStudio) is the cause of your problem. Sadly, the only solution is to either downgrade R or update RStudio. I believe you can download an installerless version of RStudio that doesn't require admin rights but I have never tried my self.

Ah I see. RStudio told me the latest version was installed but it was a lie.

I was able to install the zip version from here and it seems to run ok. Thanks!

I installed it in

C:\Users\xxxx\AppData\Roaming\RStudio\bin

Ugh now RStudio is crashing a lot.

"Javascript Alert - http://127.0.0.1:5...
R encountered a fatal error.
The session was terminated.

And it won't load the files pane.

I guess there's a conflict between the two versions of RStudio I have installed.

Yeah, it is because of their new versioning convention

Maybe it is worth filing an issue on their GitHub repo, I would give it a try

Admin installed the latest version of RStudio 2022.02.3 on my Windows.
Opening RStudio did not crash, but opening my project did crash (Javascript error).
Latest version of Javascript is already installed.
Suspected as issue with the RStudio project itself.
Deleting the projects /.Rproj.user/ directory seemed to fix it. Files pane now works.
Perhaps this is incompatible with the new RStudio.

It's still crashing occasionally with a Javascript error.
