I have a simple problem: I need to load a ERSI shapefile of US states and check whether or not a set of points are within the boundary of these states.

I am trying to set up a Grass project and need to set up the region so that I can view the map. I can look at a map and find the lat/lon, but the map projection is in UTM NAD38 WGS84 and I need to set the eastings and northings. Is there a package that will help me calculate this in R. thanks -- Stephen Sefick Let's not spend our time and resources thinking about things that are so little
