[R-sig-Geo] Point in Polygon Overlay Memory Error

[Francesco Tonini]

Dear all,

I keep getting a memory error (vector too big) when overlaying hundreds 
of thousands of points with a polygon layer. The computer I am running 
this on is quite powerful, thus the error is just internal to R because 
of reaching a vector allocation too big in size. Is there any workaround 
to execute this operation? My goal is to overlay several point onto a 
habitat polygon layer, and remove all points falling outside that polygon.

Any help is much appreciated.

Thank you,
Francesco
