[R] Random Projection

[Monaghan, David]

Hello:

I was wondering, has anyone has encountered an R package that performs random projection/random mapping?  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.
