[R-SIG-Mac] rlang and the new R version 4.1.0

[Simon Urbanek]

Hans,

you have to re-install *all* packages whenever you upgrade R. R only guarantees compatibility between patch versions (i.e. upgrading from R 4.0.0 to 4.0.1 does not require re-install, but from R 4.0.0 to R 4.1.0 does). That was always the case on all platforms, it's not new.

Note that the R Mac GUI makes the upgrade easier - in the Package Manager you can select to install package from previous R version if you use the system location. Otherwise you can always use simply 

install.packages(rownames(installed.packages("path-to-old-library")))

Cheers,
Simon
