Mapcurves: a quantitative method for comparing categorical maps.
Usage
mapcurves(x, y, z = NULL)
Value
A list with two elements:
"ref_map" - the map to be used as reference ("x" or "y")
"gof" - the Mapcurves's goodness of fit value
Arguments
x
A numeric vector, representing a categorical values.
y
A numeric vector, representing a categorical values.
z
A numeric matrix. The goodness of fit (GOF) value for each pair of
classes in x and y. By default this argument is set to NULL,
and the value of z is calculated based on x and y.
