survreg asking for parameter "special"

I don't want to speak for others, but it might be impossible to help you
without having more detail of what you did. Please provide the exact code
you used, preferedly along with some (simulated or real) sample data, that
is to say a self-contained example. If in doubt, you can look at the r-help
posting guide what is meant by that.

Betreff: [R] survreg asking for parameter "special"


Hello Gurus:
 
I'm using basic survival analysis, and trying to use survreg, and I provided
the parameter formula= and data=, but I got an error saying:
 
Error in terms.default(formula, special, data = data) :         no terms
component
I'm wondering what it's trying to say. Is it because I didn't provide
"special"? I can't seem to find what that is in the documentation.
 
Thanks!
 
Karen
