Hi

I have mone quick question I am not quite familiar with, for generic
function plot, why some methods are marked by '*', I think plot(as.mcmc()) may dispatch the right method, I try to use get to view the function, but it seems that get() only works for the one with no "*", e.g. get('plot.ecdf')

get('plot.mcmc*') doesn't work, why?

?getAnywhere



methods('plot')
[1] plot.acf*           plot.data.frame*    plot.Date*
[4] plot.decomposed.ts* plot.default        plot.dendrogram*
[7] plot.density        plot.ecdf           plot.factor*

Dear List members,
I am using R to generate MCMC time series plots.
This is the code I use; however, everytime an error message will come out
saying could not find function "plot.mcmc."
I have coda package and Lattice package installed.
Does anyone know what may get wrong here? Thanks so much for your
suggestions.

Just say plot(mcmcobject)

The plot generic should call the appropriate methode plot.mcmc that is
hidden in the code namespace.

*library (coda)
dat1=read.csv("Itemtime.csv")
col=dim(dat1)[2]
dat1=dat1[,3:col]
pdf("Itemtime.pdf")
plot.mcmc(as.mcmc(dat1),ask=FALSE)
dev.off()
