 rgeos

 it's mentioned in the R Spatial Task View:

http://cran.r-project.org/web/views/Spatial.html

but maybe:

"The rgeos package provides an interface to topology functions for sp
objects using GEOS . "

isn't obvious enough for some people to realise 'topology functions'
are what you are looking for, or are what some GIS people call
'spatial analysis' ....

The words 'overlay', 'intersect' and 'point in polygon' don't exist in
that task view...
