How can I convert OpenBUGS Coda file to mcmc object in R?

Question

I used OpenBUGS and it produced coda files of MCMC output. To calculate and plot Gelman Rubin and Geweke diagnostics, I need to convert this coda.odc file to a mcmc object in R? Is there any way to do this? Or do you recommend me some other way(s) to do this analysis?

Thanks

Ues read.coda in the coda package,... something like:

library(coda)
my.coda <- read.coda("Chain1.txt", "CODAIndex.txt")

Might work with .odc files. Defiantly works if you save the CODA files as .txt from OpenBUGS The my.coda will be a mcmc type object.
