mcmcplot1: MCMC Diagnostics Plots for one Model Parameter

Description

Creates a graph window containing three different plots---a trace plot, a density plot, and an autocorrelation plot---for one parameter in an MCMC run. This function is used by mcmcplot to construct an html file of MCMC diagnostics. This function is intended for internal use only.

Usage

mcmcplot1(x, col = mcmcplotsPalette(n), lty = 1, style = c("gray", "plain"))

Arguments

x

an mcmc object with a single variable.

col

colors for plotting each parallel chain. The default is seq(nchains)+1 where nchains is the number of parallel chains in mcmcout. If there is only one parallel chain, then the default is 1.

lty

line types for plotting each parallel chain. The default is 1 for all parallel chains.

style

if "gray", then the plotting region is printed with a gray background, otherwise the default plotting region is used.

Value

• Creates a plot.

Examples

## Create fake MCMC output
fakemcmc <- as.mcmc.list(mcmc(sapply(1:5, function(dum) rnorm(1000))))
varnames(fakemcmc) <- c("gamma[1,1]", "gamma[1,2]", "gamma[1,3]", "sigma[1]", "sigma[2]")

mcmcplot1(fakemcmc[, "sigma[1]", drop=FALSE])
mcmcplot1(fakemcmc[, "gamma[1,3]", drop=FALSE], style="plain")
