Sorry to be so persistent but I really need to get
some measure of the error in the predictions of my nls
I've tried to find out what predict.nls does and I've
got down to 
function (newdata = list(), qr = FALSE) 
    eval(form[[3]], as.list(newdata), env)
<environment: 0x88a076c>
But I can not find what is "form".
Any help, please.
