This attempts to unload and reload an installed package. If the package is not loaded already, it does nothing. It's not always possible to cleanly unload a package: see the caveats in unload() for some of the potential failure points. If in doubt, restart R and reload the package with library().

reload(pkg = ".", quiet = FALSE)



The package to use, can be a file path to the package or a package object. See as.package() for more information.


if TRUE suppresses output from this function.

if (FALSE) { # Reload package that is in current directory reload(".") # Reload package that is in ./ggplot2/ reload("ggplot2/") # Can use inst() to find the package path # This will reload the installed ggplot2 package reload(pkgload::inst("ggplot2")) }
