Origin

Origin returns (or sets) the coordinates of the point of origin of a Raster* object. This is the point closest to (0, 0) that you could get if you moved towards that point in steps of the x and y resolution.

origin(x, ...)
origin(x) <- value

Arguments

x

Raster* object

value

numeric vector of length 1 or 2

...

additional arguments. None implemented

Value

A vector of two numbers (x and y coordinates), or a changed origin for x.

#> [1] 0.5 0.0
