[R] Making a trial based Package for 30-days.

[Helios de Rosario]

I guess you could write some instructions in the "configure" file
("configure.win" for windows) at the root level of the package
subdirectory, to create a scheduled task to uninstall and delete the
package after a fixed period. That script would normally execute at the
moment of installation. See "Package structure" in "Writing R
extensions".

Yes, easy to hack. But R is free software, so that's what you should
normally expect for any mechanism. In any event, I suppose that you
don't want a "trial-based" package for your own use alone, but you want
to distribute it. And if you want to distribute it by mainstream
repositories (e.g. CRAN), you should publish the source anyway, and
won't be allowed to include such "malicious" mechanisms.
