Hi Amanze, The package is apparently "apsurvival", hosted on GitHub:
https://rdrr.io/github/carolinewei/apsurvival/ There seem to be instructions on how to install this, but the maintainer (Caroline Wei?) doesn't seem to have an email address listed. Perhaps the easiest thing for you to do is ask your teacher how to install this package and remember to load it: library(apsurvival) after installing when you need the function.
