Greetings I have a large number of long-lat locations dispersed over the US and need to identify which US county that each point is located in (or nearest to). After reading the past posts and Roger's book, I have been able to use the overlay function to identify the appropriate counties for the set of locations with long-lats lying within or on a polygon boundary. However, due to longlat precision errors (I am assuming), some of the points lie outside all of my shapefile's county polygon boundaries.
Is there an R function similar to "overlay" that I could use to find which county polygon is closest to each of my longlat points that do not lie within the shapefile's polygons? I have spent quite a bit of time searching and browsing past list discussions and can seem to find my answer. My apologies if I have missed an obvious answer.
