How can I do spatial selections or filters in R? I can do this in PostGIS using (e.g.):
SELECT * FROM mypoint, mypoly WHERE ST_Within(mypoint.geom, mypoly.geom);
and it is similarly a piece of cake in most other GIS software. So I'd expect something in R to look like:
but I can't find any leads anywhere.

Does this functionality or library exist for R? If not, is there something that is similar?
Note: In R, I use the
sp class for my objects (
