Hello
I'm trying to make survival curves for some longevity data -
100 males and 100 females, some of which are still living (not dead
at the
end of survey)
I would like to make sex specific survival curves as time on the X
axis,
proportion alive on the Y, and a line for each sex (two lines)
Data looks like this:
Focal DOB DOD Longevity Sex
1 89-04-20 na na
Female
2 54-02-20 08-04-14 54
Female
...
You should be looking at these help pages:
?read.table
?strptime
?as.Date
help(package=survival) # Which should show you where to get its
vignette.
?survfit
Any suggestions of functions to use? I've not worked with time data
(this is
yy-mm-dd) before so not sure how to handle it
Any tips and advice are greatly appreciated!
Thanks,
Rob
