function indexed weighted log-rank statistics
Hi David, Thanks, survdiff actually only has the G(rho) family, i.e. gamma is set to 0. There is another package called surv2sample, that I found only after I sent out the email, that contains what I am looking for. Thanks, Ritwik

Hi, Is there an implementation of the G(rho,gamma) class of function indexed weighted log-rank statistics in R? For example those mentioned in the paper by Kosorok and Lin (1999): The Versatility of Function-Indexed Weighted Log-Rank Statistics [JSTOR link : http://www.jstor.org/pss/2669706]. I will be very grateful if someone could point me in the right direction.
Have you looked at survdiff in the survival package ? I am not at the moment remembering the proper invocation to get authorship of a package but my memory is that this was written in S-Plus by Therneau and ported to R by Lumley. -- David Winsemius
