ReL plot(cox.zph())
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?

plot(cox.zph())
...need finite 'ylim' values
In addition: Warning messages:
1: NaNs produced in: sqrt(x$var[i, i] * seval)
2: no non-missing arguments to min; returning Inf in: min(x)
3: no non-missing arguments to max; returning -Inf in: max(x)
Can you please help me with this problem?
Many thanks,
