get_curve: Get and prepare curve

Description

load a curve of interest

Usage

get_curve(curve = NULL, verbose = FALSE)

Value

A SpatRaster or vector with curve values in a suitable format for the reconstruct function.

Arguments

curve

SpatRaster. Curve value, vector, grid or list of grids indicating the relative altitude of a biogeographic system per time period compared to the present. A typical example is a sea level curve indicating the relative sea level position above or below sea level compared to the present.

verbose

Boolean. FALSE: No messages are printed. TRUE: Standard verbose mode. 2: Very verbose mode, displaying detailed information.
