Bidensplot: Bivariate Density Plot

In QRM: Provides R-Language Code to Examine Quantitative Risk Management Concepts

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.

Examples

BiDensPlot(func = dmnorm, mu = c(0, 0), Sigma = equicorr(2, -0.7))
