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.
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

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.
