I am not aware of a function in R but you could use Grass (either as stand alone or perhaps through the spgrass6 library in R - you need to have your data in a GRASS location/mapset first) : v.what.rast in GRASS (http://www.osgeo.org/grass - open source) or try the<point sampling tool> in QGIS which is a plugin from contributed repository and you need to install it first from<fetch plugins>.
