selfStart                package:nls                R Documentation

Construct Self-starting Nonlinear Models

Description:

     This function is generic; methods functions can be written to
     handle specific classes of objects. Available methods include
     `selfStart.default' and `selfStart.formula'. See the documentation
     on the appropriate method function.

Usage:

     selfStart(model, initial, parameters, template)

Arguments:

   model: a function object defining a nonlinear model.

 initial: a function object, taking three arguments: `mCall', `data',
          and `LHS', representing, respectively, a matched call to the
          function `model', a data frame in which to interpret the
          variables in `mCall', and the expression from the left-hand
          side of the model formula in the call to `nls'. This function
          should return initial values for the parameters in `model'.

parameters, template: arguments used by some methods..

Value:

     a function object of the `selfStart' class.
