R help - May 2009 - Generating plots with two lines, each line plotted with a different color

R 2.9.0
windows xp

I would like to have the two lines generated by my plot have different colors,
in addition to the two different line types specified by the plot command below.
I would appreciate advice on how I can specify line colors.

plot(survfit(Surv(Age,Died) ~ Rx, data = GVHDdata),lty=c(1,2),lwd=2)

Thanks,
John

Try adding col=c("red","blue") as additional parameter.
