zofgrid: Utility to construct xyz-coordinates of a function for the...

In AlexanderRitz/copR: Archimedean Copulas (copR)

Description

Sets up an xy-grid, retrieves the function value at each grid point, and returns the resulting xyz-coordinates.

Usage

zofgrid(cop, FUN, n, delta, xlim, ylim)

Arguments

cop	A copula object.
FUN	character. Decides whether the cdf or pdf of the supplied copula is to be plotted. Accepts "cdf" or "pdf" as input.
n	integer. Number of grid points in x- and y-direction.
delta	double. A value in the range [0, 0.5) for changing the evaluation boundaries by adding it to the lower limits of x and y and subtracting it from the upper limits of x and y.
xlim	integer. Range of x values to be plotted.
ylim	integer. Range of y values to be plotted.

Value

A list with a vector of x-coordinates, a vector of y-coordinates and a matrix with the function values of FUN on the xy-grid.
