The base image is one of the Rocker images Dockerizing the RStudio Server IDE, further customized for the CyVerse VICE data science workbench, augmented with the standard distributed Debian package for JAGS (Just Another Gibbs Sampler for Bayesian MCMC); see: https://tracker.debian.org/pkg/jags The rjags and coda packages get pre-installed into this by the mechanism that Rocker likes to use (install2.r).
Usage outside CyVerse is similar to the base image, for example
docker run -v $(pwd):/home/rstudio --rm -p 8787:80 ltrr/vice-rstudio-jags:3.6.0
Following the convention the upstream Rocker images use, tag numbers refer to the R software version included in the image, not to Git tags in the source repository.
