[R] R Example scripts

[Gene Leynes]

Duncan,

First, thank you. It's amazing how many things R has built in... such
as these quirky functions! I really appreciate the example.

Second, as it turns out I was looking for something that doesn't exist
in bayesm, although it wasn't obvious to me until I followed your
answer and read the package web page more carefully
(http://www.perossi.org/home/bsm-1/bayesm).

I was looking for those extended examples that some packages have. For
example e1071 has a file called svn.R in the /doc folder.  Many
packages, such as formatR and hmeasure have scripts with the same name
as the package in the /doc folder. I thought (mistakenly) that those
extended examples had been moved / encoded.

For anyone searching for "bayesm examples" you may find this link
helpful, because it does have some examples and more info about the
book by Peter Rossi:
