Get Initial Parameter Estimates
.DN
This function evaluates initial parameter estimates for a nonlinear
regression model.  If `data' is a parameterized data frame or
`pframe' object, its `parameters' attribute is returned.
Otherwise the object is examined to see if it contains a call to a
`selfStart' object whose `initial' attribute can be
evaluated.

.RA
.AG object
a formula or a `selfStart' model that defines a
nonlinear regression model
.AG data
a data frame in which the expressions in the formula or
arguments to the `selfStart' model can be evaluated
.AG ...
optional additional arguments
.RT
A named numeric vector or list of starting estimates for the
parameters.  The construction of many `selfStart' models is such
that these "starting" estimates are, in fact, the converged parameter
estimates.
