Do I understand the implications of previous messages about
rattle correctlly?

=> Do I also need to use homebrew and to a full R install as is implied for Lion?

This is what I've read
R-SIG-Mac Digest, Vol 89, Issue 7   1.  Error messages when starting Rattle (Richard R. Liu)
> (R:1683): Gtk-WARNING **: Unable to find default local directory monitor type

=>  I get the same message: (R:1683): Gtk-WARNING **: Unable to find default local directory monitor type

=> I have been able to get Rattle to start, but it will do very little; does not respond to most buttons.

=> 6-core Xeon 2.66 GHz   OS X 10.6.8   R.2.13.2  rattlev 2.6.10

It's entirely different from what you get in regular R. Unfortunately it means you can't use Quartz which is already a deal-breaker for me.

Is this in reference to packages such as rgl that invoke libraries such as GTK? Are Rattle or rggobi precluded as packages?

The actual interaction depends on the details inside their rsession part - so I can't comment on that and I didn't test the packages you mention. The bottom line is that all packages are run outside the GUI in an R embedding.
