A few years ago R changed the way help was handled so that the HTML

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?
The source for the examples will be in the \examples{} section of the
.Rd source file -- that didn't change. What changed was how the source
is processed. The files are now parsed into a binary format that is
stored in the database files.
You can extract the examples from the source file using the tools::Rd2ex
function. You can extract them from the binary database using this
function on an Rd object, which is obtainable using the internal
function .getHelpFile.
So for example, to see the code for the example for rwishart, you could do
tools::Rd2ex(".../bayesm/man/rwishart.Rd")
if you have the source file installed there, or
library(bayesm)
Rd <- utils:::.getHelpFile(?rwishart)
tools::Rd2ex(Rd)
if you have the package installed.

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.
