Dear All,
when I try to reproduce an example of survexp, taken from the help
page of survdiff, I receive the error message
"Error in floor(temp) : Non-numeric argument to mathematical function"
.
It seems to come from match.ratetable. I think, it has to do with
character variables in a ratetable.
I would be interested to know, if it works for others. With an older
version of survival, it worked well.
best regards,
Heinz
