Description

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

Usage

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

## S4 method for signature '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
