I want to show students how the survival object looks like in R. Reproducible example: library(MASS) data(Aids2) attach(Aids2) status <- status=="D" stime <- death-diag surv <- Surv(stime, status) D <- data.frame(stime, status, surv) head(D,20) stime status x..i.. 1 176 TRUE 176 2 67 TRUE 67 3 432 TRUE 432 4 77 TRUE 77 5 275 TRUE 275 6 373 TRUE 373 7 389 TRUE 389 8 1027 TRUE 1027 9 492 TRUE 492 10 434 TRUE 434 11 16 TRUE 16 12 308 TRUE 308 13 92 TRUE 92 14 265 TRUE 265 15 1052 FALSE 1052+ 16 132 TRUE 132 17 527 TRUE 527 18 581 FALSE 581+ 19 511 FALSE 511+ 20 151 TRUE 151 detach(Aids2) The 'surv' column is strangely labelled 'x..i..'. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
