JAGS was developed to help those non-Window users to be able to use BUGS. However, I found it is very hard to install JAGS and its R package-rjags. Here is my note on how to install JAGS and rjags in Fedora 10. The note here should work for all Linux systems.
Compile JAGS
1. Download JAGS source code from JAGS website into any folder. The file you are looking for should look like this JAGS-1.0.3.tar.gz. The version number which might be changed if JAGS is updated.
2. Extract the tar.gz file as: tar xfvz JAGS-1.0.3.tar.gz. This will create a JAGS-1.0.3 folder that contains JAGS files.
3. Go to JAGS folder as: cd JAGS-1.0.3.
4. Do the following to install JAGS:
sudo ./configure
sudo make
sudo make install
sudo is just a Linux command that force to execute command as the administrator
5. Type jags in the terminal console to see if JAGS is installed properly. Quite JAGS by typing exit.
Install rjags
1. In the terminal console, start R as:
sudo R
2. Install rjags. In the R console, type:
install.packages("rjags", configure.args="--with-jags-include=/usr/local/include/JAGS --with-jags-lib=/usr/local/lib/JAGS --with-jags-modules=/usr/local/lib/JAGS/modules")
In each --with above, there is an empty space to separate the code.
The trick here is that rjags will ask for JAGS HEADER file, libraries and modules. So if the above code does not work, search for them and specify the right PATH in the above code.
We have also written a package called R2jags that emulates what R2WinBUGS does. But it depends on rjags. So if you have successfully installed rjags, you might want to try R2jags. It has a powerful feature which is imported from rjags that you can pick up your previous saved MCMC and update it. I have a blog entry that discuss about this feature here.
Just FYI, on Debian
ReplyDeletesudo apt-get install jags
gets you a pre-built version.
On a mac (at time of this writing) I needed to add the flag:
ReplyDeletetype="source"
Does it work for Mac?
ReplyDeleteMany Thanks,
Antonio.
Mac OS is a member of linux family. Just make sure you have the latest X11. I believe this post works for Mac users.
ReplyDeleteMany thanks,
ReplyDeleteAntonio.
sudo apt-get install jags, won't work.
ReplyDeleteinstall lapack
apt-get install libblas-dev liblapack-dev
Thank you, thank you, thank you.
ReplyDeleteThanks a lot for this tutorial. Just a small comment: If I am not mistaken, you do not need to be root to do ./configure and make. What you need to do in Step 4 is
ReplyDelete./configure
make
sudo make install
What you might want to do in Fedora prior to compiling JAGS is to type at the command line
ReplyDeletesudo yum install lapack* blas* atlas*
If you want to install rjags on 64-bit Linux, be sure to check out RogBlog. There is a solution to a common problem that shows how to put the .so files into the correct directory.
ReplyDeleteIf you have already installed JAGS on a 64-bit Linux system and now want to install rjags, an alternative to RogBlog's solution is to create symbolic links:
ReplyDeletecd /usr/local/lib64
ln -s ../lib/* .
Note that the above assumes that the only files in /usr/local/lib are those pertaining to JAGS. If there are other files in this directory, you need to manually create symbolic links for
JAGS
libjags.so
libjags.so.1.0.2
libjrmath.so
libjrmath.so.0.0.0
libjags.la
libjags.so.1
libjrmath.la
libjrmath.so.0
pkgconfig
(this list pertains to JAGS 1.0.3). The approach involving symbolic links is less elegant than RogBlog's solution, but it avoids having to recompile JAGS in case JAGS is already installed.
What a great article, i got a lot of things from here. Thanks!

So, I'm running these on MAC OS X v 10.5.8 and trying to install. I keep getting an error message because g++-4.2 is not found. Do you know if I have to install that compiler or if there's a way to get it to use the version of gcc that I currently have installed?
ReplyDeleteThanks so much!!!!
PS -- I was able to install it by updating my apple tools, and using their gcc compiler. Other distributions of gcc through the ports did not work!
ReplyDeleteTo Elana,
ReplyDeleteYou should also have the latest X11 to make the whole process works.
To avoid being root, you can use the --prefix option when installing JAGS to specify where it's installed.
ReplyDeleteWhen doing that, though, I've had to use dyn.load to load in the dynamic libraries libjags.so and libjrmath.so to get rjags to work.
Has anyone found a way around this? Can you force rjags to recognize this location during the setup?
Hi, I don't know how old this post is but I've just submitted JAGS, coda, and rjags spec & srpm files to Fedora and hope to start maintaining these programs in Fedora. If anyone is interested, I currently have the RPMs for JAGS, coda, and rjags on my blog ...
ReplyDeletehttp://cddesjardins.wordpress.com/2010/06/04/jags-package-for-fedora-13-64-bit/
After you install my JAGS rpms (both jags and jags-devel) all you need to do to install rjags is open up R and run install.packages("rjags") and everything should install fine.
I would also be interested in maintaing your R2jags program too.
I also wanted to add that there is now a i386 RPM for JAGS up on my blog as well.
ReplyDeleteHi there,
ReplyDeleteI just installed the rjags package on R 2.11.0 running on OS X 10.5.8 but when I tried to load the library I got the following error message:
library("rjags")
Error : .onLoad failed in loadNamespace() for 'rjags', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared library '/Library/Frameworks/R.framework/Resources/library/rjags/libs/i386/rjags.so':
dlopen(/Library/Frameworks/R.framework/Resources/library/rjags/libs/i386/rjags.so, 10): Library not loaded: /usr/local/lib/libjags.1.dylib
Referenced from: /Library/Frameworks/R.framework/Resources/library/rjags/libs/i386/rjags.so
Reason: image not found
Error: package/namespace load failed for 'rjags'
Does anybody have any idea how I could solve it?
Many thanks in advance,
Ruben

ReplyDeleteIf going the easy way, don't forget to install the devel stuff as well. For example on OpenSUSE, also grab:
ReplyDeletehttp://software.opensuse.org/package/jags3-devel
Even setting the paths for lib, module and include on install.packages(), it's still not working. I'm using a CentOS7. Any ideas?
ReplyDeleteThanks!
