Hi Gabor,
This is not for a regression function but for a major update I'm working on
for the summary.formula function in the Hmisc package. So I need to handle
several data types in the formula.
Thanks

Thanks for your reply Gabor. That doesn't handle a mixture of factor and
numeric variables on the left hand side.

The lattice package uses special logic to allow for multiple left-hand-side
variables in a formula, e.g. y1 + y2 ~ x. Is there an elegant way to do
this outside of lattice? I'm trying to implement a data summarization
function that logically takes multiple dependent variables. The usual
