[R-sig-Geo] spatial bounding box

2008-07-24 Thread Naiara Pinto
Dear all, I understand that the method getRasterData () from RGDAL offers the option of subsetting images by setting offset and size in terms of number of pixels. My problem is, I have images with different resolutions, so I am looking for a way to ensure subsets coincide in space. Is there a func
