yes, and the *examples* from the help pages are just run, and
not compared to prespecified output in *.Rout.save (sic!) files.
In an *installed* (not the source!) version of R or an R package 
you find the R code for all the examples from the help pages
in <pkg>/R-ex/*.R.   
That's the same for all R packages, not just the standard
