Crops spatial object x to the bounding box of spatial object (or matrix) b
This function is a cross between the spatial subsetting funtions such as sp::over(), rgeos::gIntersects() etc, and the cropping functions of raster::crop() and rgeos::gIntersection(). The output is the subset of spatial object a with an outline described by a square bounding box. The utility of such a function is illustrated in the following question: https://gis.stackexchange.com/questions/46954/clip-spatial-object-to-bounding-box-in-r/.
gclip(shp, bb)
shp |
The spatial object a to be cropped |
bb |
the bounding box or spatial object that will be used to crop |
