[R-sig-eco] Survival analysis in R

Hello all,

Does anyone know of any R packages that allow you to
create Kaplan-Meier survival functions using Pollock
et al's staggered entry design?  I've used the
"survival" package some but to my knowledge it
requires all of the subjects being entered as a single
cohort at a single time.  Thanks!
