coda_dotplot: Create a dotplot of median parameter values with 95%...

In MichaelMalick/r-codatools: codatools

Description

coda_dotplot creates a single dotplot of the specified parameters (or all parameters if none are specified) with the dots giving the median value over all mcmc chains and horizontal bars giving the 80% credibility interval (thick bars) and the 95% credibility intervals (thin bars). This type of plot is also known as a catepillar plot and provides a way to easily summarize many parameters in a hierarchical model.

Usage

coda_dotplot(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
