help to creating a points subset with R: Cut points shapefaile with a buffer polygon shapefile

Hi All Researcher, 

 

Thanks for help and suggestions. 

 

I have a points shapefile (soil) with one column [H] and a circular buffer
polygons (plots) with a column [ID identify. Ex: 1,2,3 etc etc]. I wish to
clip the points shapefile with the buffer and obtain a new points shape file
(only the points inside the buffer) with two columns [ID of buffer and H).

 

I have with maptools problem with memory because every time my R crash-down.


 

 Any suggestions would be appreciated. 

 

Thanks again

 

Ale
