done it, again, i have the next problem

my traduction:
"The object (list) cannot be corced as "double"

Original:
*km1 <- survfit(Surv(as.numeric(T.201110))~1)*
Error en Surv(as.numeric(T.201110)) : 
  el objeto (list) no puede ser coercionado a 'double'

note that need it convert to numeric class, otherwise:

*km1 <- survfit(Surv((T.201110))~1)*
Error en Surv((T.201110)) : Time variable is not numeric

I do not read that language, but I am surprised to see a single vector  
being used as an argument to Surv(). When I use Surv(. , .) it is with  
two vectors, an interval and a censor variable.

            

      
      
      
    

        
Context? Yes. We do want context, but we don't want to go to no  
steenking Nabble.

            

      
      
      
    

        
Arrrgh. The rhelp mailing list is NOT at Nabble. Nabbel si a  
commercial mirror of the real thing. And it isn't really an archive.  
either, since they start discarding posts after a year or two.
