Dear listers,
Instead of having graphs with legends composed of var-name==num, I´d
like the legens to automatically assume the name of the label
variables.
capture program drop km
program km
qui levelsof `1', local(lev)
di `lev'
foreach val of local lev {
local k `:label `1' `val''
local h `h' `val' "`1' `k'"
local m `m' lab(`val' "`1' `k'")
}
qui sts test `1'
local e=round(chi2tail(`r(df)',`r(chi2)'),0.01)
sts gr,by (`1') ti("") risktab(,title("") order(`h')) ytit("Survival")
xtit("Observation time, years") caption("* Log rank test",size(small)
span) note("P=0`e'*",pos(5) ring(0)) legend(pos(2) col(1) `m'
ring(0)) saving (`1' .gph,replace)
end
This works fine as long as the var is coded 1,2,3,4,5 etc. However if
its a binary 0/1 variable I get the error msg legend.labels[0] invalid
name.. Any idea how I can remedy this?
Regards,
M
