[R] R Example scripts

[Gene Leynes]

A few years ago R changed the way help was handled so that the HTML
files are no longer available in the library directory.  Around that
time the R example files that used to be in some of the libraries also
vanished.

I'm wondering where the "r-ex" folder went. Is it totally unsupported
and gone? Is it hidden in the mysterious rdx or rdb files?

In particular I'm looking for the latest example scripts in the baysem
package. I don't see them in the source code or the installed library.
