Getting 3.6.2 instead of 4.0 for MacOS

Hi there (@jeroen and @jimhester),

I am developing a package that requires an R version >= 4.0 (not my personal choice but an external requirement). Hence, the R CMD build fails as it seems that R version 3.6.2 is used by Travis.

Here you find my build report: https://travis-ci.com/github/saezlab/dorothea/jobs/322177438

Is there a way to specify which R version should be used by Travis or is it already planned when travis switches from 3.6 to 4.0?

Thanks for you help,
Christian

Travis is pulling R releases for OSX from https://cloud.r-project.org/bin/macosx/ . So for release and oldrel, you’ll get whatever currently is there.

See https://docs.travis-ci.com/user/languages/r/#r-versions for devel.

You can specify an exact version explicitly under r:. Available versions can be seen on the same download page and under the “old” link there.
