Hello everyone,
(This is my second question posted today on the R list).
and you have still not read the posting guide?
It asks you to provide commented, minimal, self-contained, reproducible
code which also means that you need to tell which packages you are using.
I get, e.g.:
cuminc(ftime,fstatus,group)
Error: could not find function cuminc
ftime
Error: object 'ftime' not found
fstatus
Error: object 'fstatus' not found
group
Error: object 'group' not found
Best,

I am carrying out a competing risks analysis using the cuminc function...this
takes the form:
cuminc(ftime,fstatus,group)
In my study, fstatus has 3 different causes of failure (1,2,3) there are also censored
cases (0). group has two levels (0 and 1).
I therefore have 6 different cumulative incidence curves:
cause 1, group=0; cause 1 group=1
cause 2, group=0; cause 2 group=1
cause 3, group=0; cause 3 group=1
If I type the following commands:
xx-cuminc(ftime,fstatus,group)
plot(xx,lty=1,color=1:6)
I end up with the 6 curves plotted on the same graph.
Is there a way that I can plot a selection of these curves? (say only curves
for cause 1, group=0 and cause 1 group=1).
Thank you so much,
Kind Regards,
Kim
