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!

This seems to return something that might be of interest:
RSiteSearch("survival staggered")
The first hit (of two) specifically mentions staggered entry. That might be of use? HTH G
