Is there any way that this could be made into a fortune -- perhaps by omitting the poster's identity?

"yes there are threads concidering this topic but they are all about the theory not about how to get the value of r^2 for a non-linear model in R."

Cheers,

Anna: I say this because you have just been told that the "theory" tells you that you CANNOT calculate R^2 for a nonlinear model.
