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
variables. Rejoin the
dependent variable to the data frame. Pass that to reformulate.

where R can assume that the first variable is the
dependent variable and all others are independent variables, I see no way
of processing that within the current modeling system without generating a
formula (a string) that gets parsed.

my take of the assignment was to avoid 'parse' specifically.
we start with a chara
my take of the assignment was to avoid 'parse' specifically.
we start with a character vector, so avoiding characters is not possible. i was
dealing with the fortune "if parse is the answer, you have the wrong question"
