matchExtent: Match the extent of a reference raster
In mqueinnec/foster: Forest Structure Extrapolation with R

Description Usage Arguments Details Value See Also Examples

This function crops or extends the extent of a raster to the extent of a reference. Some cells of the reference raster can optionally be masked based on their values.

matchExtent(
  x,
  ref,
  mask = FALSE,
  inverse = FALSE,
  maskValue = NA,
  filename = "",
  ...
)

`x`	Raster* object or list of Raster* objects.
`ref`	Raster* object. `x` extent will be matched to `ref` extent.
`mask`	Logical. Should x be masked by `ref` cells that have the value `maskValue`
`inverse`	Logical. If TRUE, cells of `ref` that are not `maskvalue` are masked
`maskValue`	Value of `ref` cells that should be masked in `x`. Default is `NA`.
`filename`	Character. Output file name including path to directory and eventually extension. If `x` is a list, `filename` must be a vector of characters with one file name for each element of x. Default is `""` (output not written to disk).
`...`	Other arguments passed to `writeRaster`

x and ref need to have the same CRS, spatial resolution and origin. If this is not the case, you can use matchResolution before matchExtent.

Raster* object or list of Raster* objects.
