Is there a way to find out, which R version is required for the base, stats, etc. package function I use in my package?
For instance, I used own code to get the residual SD, and later replaced it with stats::sigma(). However, sigma() requires R version >= 3.3. My package, in turn, should depend on R >= 3.2, and neither package checks, nor CRAN submission warned about the wrong specification of R dependency in my DESCRIPTION file...
