R help - Dec 2009 - Do a log rank test of two group in a fit more with more than 2 groups

Hi all,

I'm trying to find a way to get a log-rank and Wilcoxon p-value of two
single groups in a survfit() of coxph model (2 strata covariates). Is there
a quick way to this information? survdiff() does not work with coxph model.
