[R] survival anaylsis with tabulated data

[PIKAL Petr]

Hallo

I am not private consultant so please keep your messages on help list.

>From help page I understand that the function survtab_ag needs to have **specially prepared** data as input. We could only guess if your data are in correct format and most probably they are not.

Without knowing details I wonder if anybody is able to help you.

Cheers
Petr

Dear Pical,
I'm also not  an expert and had a typo error while translating colum names at code.

At my data set time(as day), at.risk(people), from0to1(as people with event), from0to0(censored values for the function) are integers, Country, and the other two columns are charecter strings.

Best regards...
Tanju

Hi

I am not an expert and cannot give you canned solution, but here are few
comments:

Without knowing data structure it is hard to decipher where is the problem.
So posting result of 
str(yourata) or at least part of it hardly anybody could help.
Cuntry is typo?
The error could by result of typo or not properly structured data.

This is plain text mail list, please do not use HTML formating.

Cheers
Petr
