Hi: I have a large data set that I'm testing and I'm finding that

Release 1.0.0 of the new R package 'randomSurvivalForest' is now available
on CRAN and its mirrors. The package implements Ishwaran and Kogalur's
Random Survival Forests algorithm for right censored survival data. The
algorithm is closely patterned after Breiman's random forests,
