Within my macro, how do I test if a plugin is installed before calling it?

I am writing a macro to capture images from a number of different cameras,
correct them for lens distortion, and stitch them together to form a mosaic.

I would like to test if a plugin is installed before calling it with
run("PluginName",...) If I call it without testing if it exists, and it is
not installed I get an ImageJ alert "Unrecognized command: PluginName".

Thanks. Alan.
