## basic usage: Surv(time, event) ~ 1
ciplot_by(time = 'futime', event = 'event', data = transplant)
## with groups: Surv(time, event) ~ group
ciplot_by('sex', time = 'futime', event = 'event',
data = transplant)
ciplot_by('sex', time = 'futime', event = 'event',
data = transplant, by = 'abo', single = FALSE)
par(mfrow = c(1, 2))
ciplot_by('sex', time = 'futime', event = 'event',
data = transplant, by = 'sex', xlim = c(0, 1500),
single = FALSE, events.total = 2100)
