Tips for debugging: R CMD check examples

Hi all,

Does anyone have any suggestions for debugging the execution of
examples by R CMD check? ?The examples work fine when I run them from
a live R prompt, but I get errors when they are run by R CMD check.

'R CMD check pkg' will produce a pkg.Rcheck/pkg-Ex.R file that
collects the examples into a single file (and also does other things).
You could try running that file interactively to see if the error is
reproduced.
