cran - Execute only check of examples and test files with `R CMD check`

Question

As runnning a full R CMD check takes a while, I am curious if there is a shortcut to only execute checking of the examples' and test files. See the part of R CMD check output I am interested in below.

I am not looking for add-on packages that would require a change of my test files (like testthat) to perform something similar. Rather, I would like to have the same stuff executed as R CMD check, i.e., generate exampels R, check differences vs. reference output (.Rout.save) and the same for test files, and procude the *.Rout files.

This would aid in package development as it speeds up testing and update of reference outputs, esp. in case of small changes.

* checking examples ... OK
* checking differences from 'pkg-Ex.Rout' to 'pkg-Ex.Rout.save' ... OK
* checking tests ...
  Running 'test1.R'
  Comparing 'test1.Rout' to 'test1.Rout.save' ... OK
  [... further test files ...]
