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.

> Hello,
> Numerous CRAN packages report minimum R versions within the Depends field
> of the DESCRIPTION file.
> Is this reporting always necessary?
> Hadley Wickham's book "R Packages" states:
> "You can also use Depends to require a specific version of R, e.g.
> Depends: R
> (>= 3.0.1) . As with packages, it’s a good idea to play it safe and require
> a version greater than or equal to the version you’re currently using.
> devtools::create()  will do this for you."
> devtools::check() doesn't warn about not specifying R version, so I am just
> curious.
> Thanks.
