Group T Status Dear R users. I am trying to program the comp()
routine in package survMisc.
1 2081 0 I am reading the data on the left with
d=read.table( "C:\\e.t.c",fill=TRUE,header=TRUE)
1 1602 0 Then I load the packages 'survival' and
'survMisc', library(survival), library(survMisc)
1 1496 0 and I run the commands
1 1462 0 s=survfit(Surv(d[,2],
d[,3])~d[,1], data=d)
1 1433 0 comp(s)
1 1377 0 and I am getting the error
1 1330 0 Error in get(t1, loc1) :
object 'd[, 2]' not found
1 996 0 If instead I use the commands
1 226 0 s=survfit(Surv(T,
Status)~Group, data=d)
1 1199 0 comp(s)
1 1111 0 routine comp() runs perfectly. However when
I am programing I can't see a way to know
1 530 0 in advance the variable names in order to
use them.
1 1182 0 Can anybody give me a suggestion?
1 1167 0 Thanks in advance
