Description

Generates eiether a perspective or a contour plot of a bivariate density.

Usage

BiDensPlot(func, xpts = c(-2, 2), ypts = c(-2, 2), npts = 50,
           type = c("persp", "contour"), ...)

function, the name of a bivariate density function.

xpts

vector, interval of x.

ypts

vector, interval of y.

npts

integer, number of subdivision points between x and y over the specified range xpts to ypts.

type

character, the plot type, either a perspective or a contour plot.

...

ellipsis, arguments are passed to the call of func.

Value

• Returns invisibly a list of (x, y, z) triplet.
