Thanks. Not what I was hoping to hear, but it's good to know. Back to
the drawing board(: Perhaps since I really don't want to allow
interactions and other exotica, I should just have the names of the
covariates passed in, and then construct the formula from that (with
paste and as.formula?).

Why is there no 'multiple-line comment code' in R,

What is your decimal delimiter ? '.' or ',' ?
If it is ',' you should change it into '.' and then as.numeric() works
just fine.
If it is '.' it won't work.

You can use as.numeric(), but you need to change the decimal delimiter
