raster (version 2.1-41)

setExtent: Set the extent of a RasterLayer

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

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

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