Dear R users.
I am trying to program the comp() routine in package survMisc.
I am reading the data below with d=read.table( "C:\\. .
.",fill=TRUE,header=TRUE)
Then I load the packages 'survival' and 'survMisc', library(survival),
library(survMisc)
and I run the commands
s=survfit(Surv(d[,2], d[,3])~d[,1],
data=d)
comp(s)
and I am getting the error
Error in get(t1, loc1) : object 'd[,
2]' not found
If instead I use the commands
s=survfit(Surv(T, Status)~Group,
data=d)
comp(s)
routine comp() runs perfectly. However when I am programing I can't see a
way to know
in advance the variable names in order to use them.
Can anybody give me a suggestion?
Thanks in advance
Endy
NB. The data must be stacked in three (3) columns before red.
They are repeated in nine (9) columns for space saving.
