Mapcurves: a quantitative method for comparing categorical maps.

mapcurves(x, y, z = NULL)

## Arguments

x A numeric vector, representing a categorical values. A numeric vector, representing a categorical values. 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.

## 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

A = floor(matrix(runif(100, 0, 9), 10))
B = floor(matrix(runif(100, 0, 9), 10))
