mycontour: Contour plot of a bivariate density function

In LearnBayes: Functions for Learning Bayesian Inference

Description

For a general two parameter density, draws a contour graph where the contour lines are drawn at 10 percent, 1 percent, and .1 percent of the height at the mode.

Usage

mycontour(logf,limits,data,...)

Arguments

logf	function that defines the logarithm of the density
limits	limits (xlo, xhi, ylo, yhi) where the graph is to be drawn
data	vector or list of parameters associated with the function logpost
...	further arguments to pass to contour

Value

A contour graph of the density is drawn
