SurvivalAtT

Read off survival rates and corresponding CIs at time T from a survfit object.

SurvivalAtT(TIMEPOINT, SVOBJECT, DIGITS = 7)

Arguments

TIMEPOINT	is the time point at which to read off the Kaplan Meier Kurves is a factorial variable
SVOBJECT,	Survival Object as produced by survfit()
DIGITS	=4, number of digits in output

Value

dataframe with SVestimate, SE, lower95.CI, upper95.CI for each arm/strata
