[R-sig-Geo] suggestion to MERGE or UNION 3 shapefiles

[Dan Putler]

All,

Why not just use the ogr2ogr command line tool included with GDAL/OGR to 
combine the shapefiles, and then bring the combined shapefile into R? 
Look at the *Examples* section on the following link to see the syntax 
on how to do it: http://www.gdal.org/ogr/drv_shapefile.html
