The OpenMx style guide says:
The first useful trick is entering the string model$ in the R interpreter and then pressing the TAB key. You should see a list of all the named entities contained within the model object
I enterd the prior script to define model, but, alas, when I enter:
model$
and press Tab
absolutely nothing happens.
I have a bog standard PC and am using R via the Gui.
Thought I must be doing something stupid and tried several times but no joy.

Yes: Not sure where that claim came from - I have not seen it as an R behavior either.
It seems that it works in Emacs with ESS.
It works in the Mac OS-X terminal window. You do need to press tab twice. The first time does nothing. The second tab press brings up the list of possibilities.
It doesn't work in the Mac OS-X R-64 GUI.
How tab completion works is dependent on which console you are using.
I personally work in R using TextMate for the editor and Terminal (with tcsh and emac keys turned on) on Mac OS-X. I like this the best out of all of the combinations I've tried. As they say, YMMV.
Under Windows 7, in the RGui running R 2.10.1 and with mxVersion() reporting 0.2.10-1172, I observe the same behavior as Steve reported in the Mac OS-X terminal.
