setExtent: Set the extent of a RasterLayer

In raster: Geographic Data Analysis and Modeling

Description

setExtent sets the extent of a Raster* object. Either by providing a new Extent object or by setting the extreme coordinates one by one.

Usage

setExtent(x, ext, keepres=FALSE, snap=FALSE)
extent(x) <- value

Arguments

x	A Raster* object
ext	An object of class Extent (which you can create with extent, or an object that has an extent (e.g. a Raster* or Spatial* object) )
keepres	logical. If TRUE, the resolution of the cells will stay the same after adjusting the bounding box (by adjusting the number of rows and columns). If FALSE, the number of rows and columns will stay the same, and the resolution will be adjusted.
snap	logical. If TRUE, the extent is adjusted so that the cells of the input and output RasterLayer are aligned
value	An object of class Extent (which you can create with extent )

Value

a Raster* object

Examples

r <- raster()
bb <- extent(-10, 10, -20, 20)
extent(r) <- bb
r <- setExtent(r, bb, keepres=TRUE)
