Rescale a SpatVector or SpatRaster. This may be useful to make small inset maps or for georeferencing.

Usage

# S4 method for class 'SpatRaster'
rescale(x, fx=0.5, fy=fx, x0, y0)

# S4 method for class 'SpatVector'
rescale(x, fx=0.5, fy=fx, x0, y0)

Arguments

x

SpatVector or SpatRaster

fx

numeric > 0. The horizontal scaling factor

fy

numeric > 0. The vertical scaling factor

x0

numeric. x-coordinate of the center of rescaling. If missing, the center of the extent of x is used

y0

numeric. y-coordinate of the center of rescaling. If missing, the center of the extent of x is used

Value

Same as x
