Hi, Sorry to trouble the list - I would like to ask a question - I can't find the answer in the r-help archives. I am trying to plot 2 survival curves in different colors. What I have tried is this plot(survfit(sim.surv ~ sim.km.smpl),col="red") but both the survival curves turn red... Your advice would be most appreciated! Thank you. Min-Han
Try plot(survfit(sim.surv ~ sim.km.smpl), col=c("red", "blue")) --Matt -----Original Message----- From: r-help-bounces at stat.math.ethz.ch [mailto:r-help-bounces at stat.math.ethz.ch]On Behalf Of Min-Han Tan Sent: Sunday, July 25, 2004 12:10 PM To: r-help at stat.math.ethz.ch Subject: [R] Colors in survival plots Hi, Sorry to trouble the list - I would like to ask a question - I can't find the answer in the r-help archives.

For example library(survival) data(ovarian) plot(survfit(Surv(futime,fustat)~rx, data=ovarian), col=c("goldenrod","forestgreen")) -thomas
