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)))))

## caterplot plots of the fake MCMC output
par(mfrow=c(2,2))
caterplot(fakemcmc, "alpha", collapse=FALSE)
caterpoints(runif(5, -0.1, 0.1), pch="x", col="red")
caterplot(fakemcmc, "alpha", horizontal=FALSE)
caterpoints(runif(5, -0.1, 0.1), horizontal=FALSE, pch="x", col="red")
