Superpc:

Supervised principal components software for R

Authors: Eric Bair and Rob Tibshirani
Maintainer: Rob Tibshirani

This software, written in the R language, does prediction for a censored survival outcome, or a regression outcome, using the "supervised principal component" approach. It is especially useful when the number of features p is >> n, the number of samples, for example in microarray studies.
