Strang line while plotting failure curves
Dear R helper,
I encountered a problem when I tried to plot the cumulative failure rate
(i.e. 1 - survival probability). I have used the following code to plot. The
scenario is that patients are randomized to different treatment arm (rev in
the code), the PCI revascularization was monitored over 5 years.
#R code
testfit <- survfit(Surv(pcifu,pci)~rev,data=subproc)
testfit$surv <- 1 - testfit$surv
testfail <- plot(testfit, mark.time=FALSE,col=1:2, main='Failure Rate')
#End of R code
I arbitarily replaced testfit$surv by computing 1 minus the original...
