Hello,
I apologize for the post as I am certainly overlooking a simple
solution to my difficulties with getting a legend to print on a
survplot from the rms package.
I am plotting the following:
survplot(survest(fita), n.risk=T, conf='none', cex.n.risk=.85, dots=T,
col='gray10', lty=2)
survplot(survest(fit), n.risk=F, conf='none', add=T)
survplot(survest(fitb), n.risk=F, conf='none', col='gray20', add=T,
lty=4)
I have tried to place 'label.curves=list(method="arrow", cex=.8)' and
others as suggested in ?survplot in any and all of the above commands,
but I do not get a legend regardless of whether I try to plot only one
or several lines as above. Any suggestions as to how I can generate a
legend would be greatly appreciated.
Thanks, Aric
Please send exact code for an example that fails. If possible, generate
the data using a simple simulation to make the example reproducible.
