The error arises because you loaded package coda
after loading jagsUI
, which is clear from your sessionInfo
output. When you did that, you should have seen a message:
The following object is masked from ‘package:jagsUI’:
traceplot
So when you do traceplot(out5)
you are calling coda::traceplot
, not jagsUI::traceplot
. And, yes, that only works with valid mcmc
objects, while out5
is class jagsUI
.
There's no call to library(coda)
in the script, so it's not a bug. On the other hand it is called in 11.07, so maybe good to specify jagsUI::traceplot
everywhere in chapter 11.
The library(coda)
call in 11.07 is unnecessary, so I have removed it (commented it out).
Sorry for the confusion, and thanks for helping out with this!

Thank you for reporting a bug in our scripts.
The code here is based on the book, and we update it to work with current versions of JAGS, R and R packages. Please make sure you have the latest version of the script and software (run
update.packages()
) before reporting an issue.File name: AHM1_ch11
Lines which produced the error or unexpected output (copy/paste from the console): op <- par(mfrow = c(4,4)) ; traceplot(out5) ; print(out5, dig = 3)
error message: Error in mcmc.list(x) : Arguments must be mcmc objects
Do you have a suggested update for the code:
Coda specifies that in the updated version, older mcmc objects will result in an error message. "n previous releases of CODA, an mcmc object could be a single or multiple chains. A new class mcmc.list has now been introduced to deal with multiple chains and mcmc objects can only have data from a single chain."
mcmcUpgrade(x) can be used to update outdated code for mcmc objects; or objects could be modified to specified correctly under the updated version of the coda package
