The Windows installer writes some keys in the Windows registry. These keys are then read by the rjags package when it is loaded to locate the JAGS DLL. I don't know why this is not working in your case. You might try uninstalling and reinstalling JAGS (and by this I mean that the user who installed it should uninstall it from the Control Panel). Otherwise, as David says, you can set the environment variable JAGS_HOME. Note that if you previously set JAGS_HOME in .Rprofile and have upgraded to a new version of JAGS, then JAGS_HOME will be pointing to the wrong place. This might explain why rjags cannot find JAGS and this is why I do not recommend this solution except as a last resort. > You might try to use Sys.setenv to create a properly directed JAGS_HOME > > Sys.setenv(JAGS_HOME=“C:\programs\JAGS\JAGS-4.0.0”) > > (I corrected the semi-colon.) > >> library(rjags) > > Error : .onLoad failed in loadNamespace() for 'rjags', details: > > call: fun(libname, pkgname) > > error: Failed to locate any version of JAGS version 4 > > > > The rjags package is just an interface to the JAGS library > > Make sure you have installed JAGS-4.x.y.exe (for any x >=0, y>=0) from > > http://www.sourceforge.net/projects/mcmc-jags/files > > I’m was having a perhaps similar problem on a Mac.

Unfortunately the Mac OS X binaries on CRAN are not up to date. I have no control over this but Matt Denwood has made a binary for Mavericks or later available on Sourceforge: http://sourceforge.net/projects/mcmc-jags/files/rjags/4/rjags_4-4.tgz Martyn > Going back to SourceForge and tracking down the older version of JAGS > and installing version 3.4.0 was successful in getting rjags to load > correctly.
