Question: I need an input mechanism to allow a user to create a single-level bullet list. I can't trust the user's ability to know HTML formatting or to not mess it up if auto-formated. I've been debating using a wysiwyg editor, but that doesn't force a bullet list.

I have jQuery installed, but can use other options.

Answer: 
I found (after downloading and installing the dmg from [SourceForge](http://sourceforge.net/projects/mcmc-jags/files/)) that the following commands worked for me:

```
wget http://cran.r-project.org/src/contrib/rjags_2.2.0-4.tar.gz
wget http://cran.r-project.org/src/contrib/R2jags_0.02-15.tar.gz
sudo R --with-jags-modules=/usr/local/lib/JAGS/modules-2.2.0 CMD INSTALL rjags_2.2.0-4.tar.gz
sudo R --with-jags-modules=/usr/local/lib/JAGS/modules-2.2.0 CMD INSTALL R2jags_0.02-15.tar.gz
sudo R --with-jags-modules=/usr/local/lib/JAGS/modules-2.2.0 --arch=i386 CMD INSTALL rjags_2.2.0-4.tar.gz
sudo R --with-jags-modules=/usr/local/lib/JAGS/modules-2.2.0 --arch=x86_64 CMD INSTALL rjags_2.2.0-4.tar.gz

```

They certainly aren't all necessary, but they were sufficient!
I encountered the error: unable to load shared object '/Library/Frameworks/R.framework/Resources/modules//R\_X11.so': on my Mac and DuckDuckGo led me to this post. I was using R from the command line, so I can't speak to how it works with RStudio although I'm pretty sure it's the fix for that too. I updated JAGS from [the SourceForge link](http://sourceforge.net/projects/mcmc-jags/files/) provided in another answer. I can at least verify that it worked for me, though the developer was unsigned (I needed to ignore a MacOS warning during the installation procedure).
