there should be an example in the VMD user's guide for how you can loop
over a trajectory. Now all you would have to do is to adapt that for use
with the "measure rgyr" command.
I am certain that the plugin you are looking for is doing something very
similar, but just gets some of the script parameters from a GUI (like so
many other VMD plugins with a GUI do).
