Thanks, Rich.
I thought of that, too, but it violates the spirit of my restraints (to
avoid character strings), which I unfortunately did not clearly articulate.
So my apologies for that failure. My concern is that with more complex
model formula, using as.formula, etc. to parse/convert character strings
can get a bit hairy. But in most cases, as here maybe, it may be perfectly
fine. So think of my post as mostly my attempt to learn some new tricks
rather than to solve a useful problem. I hope this is not unfair to the
list.
Cheers,
Bert
