Problems with R and Big Sur

Dear all,

I am running R 4.0.3 on BigSur without major performance issues. I am using RStudio instead of the R GUI.

I had to build all spatial packages (rgdal, sf, terra and raster) from source using the Apple clang version 12.0.0 compiler. I also had to build GDAL from scratch, since neither the ?homebrew? version nor the ?kyngchaos? version work well with BigSur.

If anyone is building packages from source, please make sure to have installed the latest version of Apple?s development environment, including version 12.0 of the compiler as earlier versions do not work well in BigSur.

Best

After a bit of git and google poking it seems this is happening to users
of MacVim (https://github.com/macvim-dev/macvim/issues/1114) and a few
other FOSS projects.

In various GH issues (like that one) the issue claims to be resolved by
using the latest Xcode & SDK but that?s not likely to be a solution for R
GUI (which I?m assuming you're using and where this error is coming up).

Some of the threads I saw made it seem like it was happening especially on
Touch Bar-equipped MacBook Pros (but that?s not confirmed).

When I try R GUI on Big Sur (on the new M1 Mini) ? either just plain R
scripts or plotting ? I do not see this, nor do I see this on my Intel
MacBook Pro (both are on the latest Big Sur beta and R 4.0.3).

I didn't get this with R 4.0.3 under macOS Big Sur 11.0.1 with "time
R CMD build" / check.  I have not tried it under RStudio.

I don't get this in 4.0.3 (using the command line version of R) and I

don't get this in RStudio 1.3.1093 either.  I use the homebrew versions

without the R GUI even installed.


I am sure more detail will be helpful to the developers.

To those in charge of R for Mac OS X:

I have installed the new Big Sur operating system and now I always get

a warning similar to:

2020-12-02 09:52:00.647 R[703:11786] Warning: Expected min height of

view: (<NSPopoverTouchBarItemButton: 0x7f9c6bb3df50>) to be less than

or equal to 30 but got a height of 32.000000.  This error will be

logged once per view in violation.

and the computer becomes very slow.

Can I do something to fix it, or will we have to wait for an R update?

Thank you very much for your attention.

Sincerely,

Mar?a-?ngeles Casares-de-Cal
