traplot1: Trace Plot for a Single Parameter in MCMC Output

Description

Creates a trace plot for one parameter in an MCMC simulation. This function is called by the mcmcplot function, and is intended for internal use only.

Usage

traplot1(x, col = mcmcplotsPalette(nchains), lty = 1, style = c("gray", "plain"), ...)

Arguments

x

an mcmc.list object with a single variable.

col

one or more colors for the trace lines.

lty

one or more line types for the trace lines.

style

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

...

further arguments passed to the plotting function.

Value

• Creates a plot.

Examples

## Create fake MCMC output
nc <- 10; nr <- 1000
pnames <- c(paste("alpha[", 1:5, "]", sep=""), paste("gamma[", 1:5, "]", sep=""))
means <- rpois(10, 20)
fakemcmc <- as.mcmc.list(lapply(1:3, function(i) mcmc(matrix(rnorm(nc*nr, rep(means,each=nr)), nrow=nr, dimnames=list(NULL,pnames)))))

traplot(fakemcmc[, "alpha[5]", drop=FALSE])
traplot(fakemcmc[, "alpha[5]", drop=FALSE], style="plain")
