Description Usage Arguments Details Value Author(s) See Also Examples

The function retrieves the survival probabilities from a survfit object, for a specific point in time.

1	getsurv2(sf, time, which.est = c("point", "lower", "upper"))

`sf`	`survfit` object
`time`	time at which the survival probabilities must be retrieved
`which.est`	which estimation to be returned? `point` for the point estimate, `lower` for the lower bound and `upper` for the upper bound

The survival probabilities are estimated through the survfit function.

vector of survival probabilities
