coda_histogram: Create a histogram of marginal posterior distributions

In MichaelMalick/r-codatools: codatools

Description

coda_histogram uses the histogram function in the lattice package to plot histograms of the marginal posterior distribution for each parameter specified by the parameters argument. In addition, a density overlay, rug of mcmc sample values, median value (bold vertical dash), and 95% credibility interval (bold horizontal line) are plotted. The function uses lattice to panel the histograms for each parameter.

Usage

coda_histogram(coda.object, parameters = NULL)

Arguments

coda.object	An mcmc.list object
parameters	character vector of parameter names to include in graphic. If none are supplied all monitored parameters are included.

Value

A graphics device

               value = TRUE)))
