DESCRIPTION:

This method function extracts the common nonlinear model formula associated with each nls component of object.

USAGE:

formula(object) 

REQUIRED ARGUMENTS:

object
an object inheriting from class nlsList, representing a list of nls objects with a common model.

VALUE:

a two-sided nonlinear formula specifying the model used to obtain the nls components of object.
