Hi everyone, 

Its have been very difficult to do an spatial join with R and I couldn't find any good manual about it. So, I will explain it if someone is willing to help.

I have one Shapefile with poligons (with its number) and another Shapefile with xy points. My idea is to obtain the number of the polygons where the points are found, in order to obtain their social data of those polygons.

How can I do it? Is there any good way to do it? Where can I find informationa bout it? Any function?

Thanks in advance
José
