mycontour {LearnBayes}

Contour plot of a bivariate density function

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
