If sdf <- survdiff(...) is your survdiff object, the p-value can be computed as follows:
p.val <- 1 - pchisq(sdf$chisq, length(sdf$n) - 1) and then use it in your K-M plot. -Christos Christos Hatzis, Ph.D. Nuvera Biosciences, Inc. 400 West Cummings Park Suite 5350 Woburn, MA 01801 Tel: 781-938-3830 www.nuverabio.com > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Armin Goralczyk > Sent: Thursday, April 26, 2007 3:03 PM > To: [email protected] > Subject: [R] Extract p-value from survdiff function > > Hi list, > I want to use the p-value from the survdiff function (package > survival) to reuse within a function in a Kaplan-Meier plot. > The p-value is somehow not a component of the value list ?! > > Thanks in advance > -- > A.
