### Usage

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

### Arguments

`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
