Arguments

x

SpatRaster or SpatVector

wide

logical

xy

logical

cells

logical

mode

this argument is ignored

trunc

logical; truncate values to integers. If FALSE the object returned can be very large

dissolve

logical; combine cells with the same values?

values

logical; include cell values as attributes? If FALSE the cells are not dissolved and the object returned can be very large

crs

character. The coordinate reference system

...

additional arguments. None implemented

Value

vector, matrix, array, data.frame or SpatVector

Examples

# NOT RUN {
r <- rast(ncol=2, nrow=2)
values(r) <- 1:ncell(r)

as.vector(r)
as.matrix(r)
as.matrix(r, wide=TRUE)
as.data.frame(r, xy=TRUE)
as.array(r)
as.points(r)

if  (gdal_version() >= "3.0.0") {
	p <- as.polygons(r)
	p
	as.lines(p)
	as.points(p)
}
