R CMD <custom>?

It'd be cool if R CMD was user extensible through packages, so that (e.g.)

R CMD mypackage::mycommand

would do something like:

path <- system.file("cmd", paste(command, ".r"), package = package)
if (!file.exists(path)) {
  stop("Command ", command, " in ", package, " does not exist")
} else {
  source(path)
}

And maybe `R CMD mypackage` would look in mypackcage/cmd/default.r.

Hi,

is it possible to add a custom script such that it is called via R CMD
<custom>? ?Is R CMD searching for it elsewhere than R_HOME/bin/? ?I'm
looking for an non-admin alternative, so copying the script to
R_HOME/bin/ will not do (in case the user don't have enough permission
to write there).

/Henrik
