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,
