rescale function

rescale

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

## 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
