Bivariate Density Plot

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"), ...)

Arguments

`func`	`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.
