[Rd] bug in survival package basehaz function (PR#1266)
Hi,
In the survival analysis package the function basehaz has 2 errors in the
last line
return(data.frame(hazard=H,time=surv$time,strata=strata))
1) no object surv is created or passed to the function, it should be sfit
2) If there are no strata data.frame barfs bucause strata is NULL
the following is a work around, there may be a better way.
if(!is.null(strata))
return(data.frame(hazard=H,time=sfit$time,strata=strata))
else
return(data.frame(hazard=H,time=sfit$time))
below is all the version info.
