[R] Install package automatically if not there?

[Law, Jason]

Something like:

if (!require(pkg)){
	install.packages(pkg)
}

Hi fans,

is it possible for a script to check if a library has been installed?
I want to automatically install it if it is missing to avoid scripts to crash when running on a new machine...
