Jim,
Try here: <http://www.sitmo.com/doc/
Generating_Correlated_Random_Numbers>; the example code is in matlab,
but it is trivial to translate to R. Note, if you use principal
components as the source vectors (thanks to Jason Tangen for the
suggestion), the correlations between the resulting vectors will be
exactly the specified r-values.
