I think you tried to start JGR from the console, which will usually not work. JGR has to be started using the launcher which is available at http://jgr.markushelbig.org/Download.html
The irmb function will not only need the package installed, but also requires you to use the JGR console for your session. (because iWidgets depends on it) I will include some more detailed information on that in my help files in the next version.
