JAGS 3.4.0 for Mavericks

Thanks to Matt Denwood, we now have a binary distribution of JAGS 3.4.0 for Mac OS X Mavericks. There is a separate binary for older Mac OS X releases (Snow Leopard, Lion, Mountain Lion). Both binary packages can be downloaded from the files page.

[Update 2014-09-11] The rjags package for Mavericks is now available from CRAN. To make it work, you need to have the right combination of R and JAGS:

  1. If you installed the R-3.1.1-mavericks.pkg version of R then you need to install JAGS-Mavericks-3.4.0.dmg
  2. If you installed the R-3.1.1-snowleopard.pkg version of R then you need to install JAGS-SnowLeopard-3.4.0.dmg

If you get an error about a missing symbol then you have the wrong combination of R and JAGS.

[Update 2014-11-28] Note that if you are running Mavericks or Yosemite then you cannot assume that you are running the  “Mavericks” version of R, as the “Snow Leopard” version also runs on the latest releases of Mac OS X. If you are not sure which R binary package is installed then type


at the R prompt (note the dot at the beginning). This will either say mac.binary or mac.binary.mavericks. Follow the corresponding link to get the right binary version of JAGS to match your R installation.

If you are still having problems, come to the JAGS forums.
