I am seeking information on whether anyone has written code to perform Horn's parallel analysis (a procedure that informs the selection of the proper number of components in PCA) in R. Thank you in advance for any help you can provide. Please respond off-list at the email address below.

Dear Karen,
You should find the code you want in the package paran:
http://cran.r-project.org/web/packages/paran/index.html
And you may be interested in looking at the Multivariate Cran Task view which
attempts to catalogue these kinds of things:

I am seeking information on whether anyone has written code to perform
Horn's parallel analysis (a procedure that informs the selection of the
proper number of components in PCA) in R.
Thank you in advance for any help you can provide. Please respond
