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 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)
