Want to unload a package without restarting R? It is possible to have multiple versions of a package loaded at once (for example, if you have a development version and a stable version in different libraries). To guarantee that all copies are detached, use this function.
1 2 3 4 5 6 7 8 9 10 11 12 | 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) } } |
