[R] ReL plot(cox.zph())

[Terry Therneau]

You report an error message:

> plot(zph.revasFit[1])
Error in plot.window(xlim, ylim, log, asp, ...) : 
        need finite 'ylim' values

I have never seen this error before, and I cannot guess what causes it.  You
need to provide more information, and likely a small data set that produces
the problem.  Perhaps you have an x variable that is a constant?
