autoload {base} | R Documentation |
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.
.Autoloaded
contains the “base names” of the packages for
which autoloading has been promised.
autoload(name, package, reset = FALSE, ...) autoloader(name, package, ...) .AutoloadEnv .Autoloaded
name |
string giving the name of an object. |
package |
string giving the name of a package containing the object. |
reset |
logical: for internal use by autoloader . |
... |
other arguments to library . |
This function is invoked for its side-effect. It has no return value as of R 1.7.0.
