You can also crop a SpatVector with a rectangle (SpatRaster, SpatExtent). Unlike with intersect the geometries and attributes of y are not transferred to the output. If these are not polygons, the minimum convex hull is used). You can crop a SpatVector with another SpatVector. See methods like resample and disagg to force SpatRasters to align and extend to add rows and/or columns. Also note that the SpatRaster returned may not have the exactly the same extent as the SpatExtent supplied because you can only select entire cells (rows and columns), and you cannot add new areas. You can only crop rectangular areas, but see mask for setting cell values within SpatRaster to NA. densify: Add additional nodes to lines or polygonsĬut out a part of a SpatRaster with a SpatExtent, or another object from which an extent can be obtained.crs: Get or set a coordinate reference system.crds: Get the coordinates of SpatVector geometries or SpatRaster.cover: Replace values with values from another object.convhull: Convex hull, minimal bounding rotated rectangle, and minimal.concats: Concatenate categorical rasters.compareGeom: Compare geometries of SpatRasters.compare-generics: Compare and logical methods.collapse: tighten SpatRaster or SpatRasterDataset objects.coerce: Coercion to vector, matrix or array.classify: Classify (or reclassify) cell values.cellSize: Area covered by each raster cell.

RasterLayer or RasterBrick object or SpatialLines or SpatialPolygons object. To crop by row and column numbers you can create an extent like this (for Raster x, row 5 to 10, column 7 to 12) New Extent objects can also be created with function extent and drawExtent by clicking twice on a plot.

You can check this with the extent function. Objects from which an Extent can be extracted/created include RasterLayer, RasterStack, RasterBrick and objects of the Spatial* classes from the sp package.

Usage # S4 method for signature 'Raster'Ĭrop(x, y, filename='', snap='near', datatype=NULL. Areas included in y but outside the extent of x are ignored (see extend if you want a larger area). If x is a Raster* object, the Extent is aligned to x. Crop returns a geographic subset of an object as specified by an Extent object (or object from which an extent object can be extracted/created).
