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
packages.

I'll expand a bit on Martin's comment. It is hard to test the output of
all examples because some examples use random numbers, and for others
the precision may vary a bit on different platforms. I typically add
important examples to the tests directory, set the random number
generation, and compare results within tolerances that work on different
platforms.
