This is what I usually do:
(points is a dataframe with x and y columns)
library("sp")
coordinates(points)=~x+y
polygon<-readShapePoly("shapefile.shp")
a<-overlay(points,polygon)
# a will contain the id's of the polygons per point
# . to get the attributes for every point I use:
polygon[a,[EMAIL PR

have been unable to find a solution. Your help with this is appreciated.
