[R-pkg-devel] (Not) Reporting minimum R version in DESCRIPTION Depends Field

[Hadley Wickham]

I no longer believe this to be good advice - I think you should only
declare a specific dependency if you want to strongly assert that your
package works with those versions. For example, all tidyverse versions
depend on R 3.2 and later, because we test on all those versions.
