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.
