I suggest reading the chapter on debugging in 'Writing R Extensions' and
using the tools described there (such as options(error=recover)) would be
at least as effective. Even traceback() would have helped the readers.
Note that there is no function 'cph' in R: presumably we are supposed to

For me, the simplest way to find, what is wrong, would be tracing the R code:
library(debug)
mtrace(cph)
cph(Surv(time.sur, status.sur)~ strat(colon[,13])+colon[,18]
+colon[,20]+colon[,9], surv=TRUE)
... then find the place of the error and analyze how to adjust the function

Dear R users,
I tried to fit a cox proportional hazard model to get estimation of stratified
survival probability. my R code is as follows:
cph(Surv(time.sur, status.sur)~ strat(colon[,13])+colon[,18]
+colon[,20]+colon[,9], surv=TRUE)
Error in if (!length(fname) || !any(fname == zname)) { :
