On-demand Loading of Packages
Description
autoload creates a promise-to-evaluate autoloader and stores it with name name in
.AutoloadEnv environment. When R attempts to evaluate
name, autoloader is run,
the package is loaded and name is re-evaluated in the
new package's environment. The result is that R behaves as if
file was loaded but it does not occupy memory.
