Replace the soon-to-be Design with rms.
Specify surv=TRUE to cph so that approximate rather than fully correct
standard errors will be computed by survplot/survest.

Hi,
I have a Cox PH model that's large for my server, 120K rows, ~300 factors
with 3 levels each, so about 1000 columns. The 300 factors all pass a

Design takes about 3 hours. I have created the fit with x=T, y=T to save
