R help - Jun 2002 - fit with parameters under some condition

Hello!


I'd like to fit with nls some function, say,

    y(x, p);   p = c (p1, p2)

with fit parameters bound certain condition, in genegal case,

    F (p1, p2) = 0.

Or, in particular case,

    p2 = f(p1).


Is there 'most right' way to do it?

Thank you very much,

Timur.

Fit it as p = c(p1, f(p1))
