[R] Coefficient of determination

[Bert Gunter]

For linear, yes: ?summary.lm

For nonlinear, no, since there is no such thing (unambiguously, anyway) in
nonlinear regression.

It's almost always a bad idea even in linear regression, though.

Subject: [R] Coefficient of determination

Dear all,

Is there a instruction that can help me obtain the coefficient of
determination R^2 after doing linear/nonlinear regression using lm/nls?
