Hi folks,

I need to perform a certain map-based task in R, and I'm hoping that
someone can point me towards the right package or approach:

I have lat/long coordinates that specify the corners of a polygon, and I
need to be able to draw a grid within that polygon where the points of the
grid are regularly spaced at intervals I determine.  Then I want to extract
that list of points from the grid (so that I can send people out to take
samples at those grid points).

I've been looking around, and the closet thing I've seen is map.grid
{mapproj}, which seems to be restricted to a shape defined by 4 points
rather than a many-sided polygon which is what I need....

Any pointers would be very welcome!
thanks
Matt
