RP is a procedure that is akin to Principal Components Analysis in that it accomplishes dimensionality reduction, but is far more computationally efficient.  I have been searching for some time, but haven't seen anything on CRAN-r yet.  

The experimental "wordspace" package available from R-Forge has an implementation of RI in the dsm.projection() function.  See


for download / installation.
