plottarget3d {EntropyMCMC}

R Documentation

3D plot of a two-dimensional MCMC target, or any function

Description

Utility function for the package EntropyMCMC, to visualize a 2-dimensional target of a MCMC algorithm, mostly for testing purpose. This uses the function persp from package graphics.

Usage

plottarget3d(zft, l, r, ms, theta, phi, ...)

Arguments

zft	a function, typically a 2-dimensional target of a MCMC.
l, r, ms	mesh boundaries and size.
theta, phi	angles defining the viewing direction. theta gives the azimuthal direction and phi the colatitude.
...	additional graphical parameters.

Value

Returns a 3D plot on a mesh of size (l, r, ms).
