Paul Murrell offered some worked examples of using paths from vector
graphics in the articles and talks he has given for the grImport
package:

Hi useR's,
I have an image plot I want to overlay a map of the United States
on, via
map('usa'). The image is basically a large rectangular of various
colors.
When I overlay the United States map, the full rectangle of the
image plot
is visible, but I only want to display the image WITHIN the United
States
boundary.
Does anyone know a way to do this?
Thanks in advance,
dxc13
