The argument to survplot should be a cph or psm or survfit object (or
a survest result on a psm object).
My apologies, all that and I made a typo. I have been doing:
survplot(survfit(fit.example1), n.risk=...)
But fit.example1 is a cph object. It can go directly to survplot.
Best to take a break and read over more documentation.
Perhaps this is still incorrect?
It does plot, but no legend, so it is likely incorrect. Trying to plot
the cph object does not work for me. I get an error about the datadist
not including the data. I did make a datadist that is the master
dataframe of which what I am trying to plot is a subset thereof.
Best to do that first, after require(rms).
Please read the posting guide also.

Thanks, Aric
