How can I unload a package without restarting R? I tried library but it doesn’t show any options that would unload the package. I also tried detach but it also failed: detach(ans) Error in detach(ans) : invalid name argument detach("ans") Error in detach("ans") : invalid name argument So How can I perform this task? Select the correct answer from above options

Try this using ?detach: detach("package:ans", unload=TRUE) Alternatively you can also use unloadNamespace command unloadNamespace("ans") For multiple versions of a package loaded at once use detach_package <- function(pkg, character.only = FALSE) { if(!character.only) { pkg <- deparse(substitute(pkg)) } search_item <- paste("package", pkg, sep = ":") while(search_item %in% search()) { detach(search_item, unload = TRUE, character.only = TRUE) } } In your case either use detach_package(ans) or use detach_package("ans", TRUE) Thank you for reading this answer.
