 More minimally than the click function, there's always the locator
function which lets users click on the current plot and returns the
coordinates. Then you can do whatever you want with those coordinates,
including testing against a set of polygons to see which one the user
clicked on.

 The direction that this thread seems to have gone in (now we're on
geo web servers and REST APIs to R-in-the-cloud SaaS providers) seems
a little over the top for a 'please choose a region' query.
