smcure package error

Question

I would like to perform a cure analysis, and when I run the code below:

pd <- smcure(Surv(FAILTIME,FAILCENS)~trt+Age1 , cureform =~trt+Age1 ,data=saba, model="ph",nboot=1000)

This error is reported:

Error in rep(1, n) : invalid 'times' argument

Answer 1

This error is most likely due to an NA in your dataset.
