Wow .. that is beautiful :-) .. and exactly what I was looking

I ended up doing this:

No need for the vars variable. Though admittedly it breaks down if

Hello,
Still a newbie with R, though I have learned a lot from reading
this list. I'm hoping someone can help with this question:
I have two vectors, one for variables, and one for bits.
I want to build a string (really a formula) based on the values in my
vector of 1s and 0s in bits. If I have
