labels.eoa - Extract parameter labels from eoa objects.

1 2	## S3 method for class 'eoa' labels(obj, type = "coef")

`obj`	An `eoa` model object. See `eoa`.
`type`	The type of parameter label requred or a regular expression. Parameter type possibilities are "coef" or "derived". Regular expressions are used to match parameter labels using `grep`. If `type` is not "coef" and not "derived" and the regular expression fails to match anything, all parameter labels.

Coefficient labels are for variables in the log-linear model for lambda. Derived parameter labels are non-coefficient parameters link M, Mtot, and lambda.
