[R-SIG-Mac] Updating packages from RStudio

[Gábor Csárdi]

Since car was released not so long ago, I am fairly sure that this is
an issue with the CRAN metadata, similar to what I (and many others)
see for newly released packages:
https://stat.ethz.ch/pipermail/r-sig-mac/2026-February/015335.html

I wrote some code to show the packages for which the metadata is inconsistent:
https://gist.github.com/gaborcsardi/797472e42b43d2f938f852614f2a170f
(Update the URL for a different arch or R version.)
Seems like car should be fine now, assuming this already propagated to
your mirror.

FWIW AFAIR all RStudio does is calling install.packages() so if you
see a 404 there, it is unlikely that it is a problem with RStudio.
Nevertheless I agree that it is always a good idea to test your code
in a plain R console.
