as.parameters: Generic Method for Converting Objects into 'parameters'
Description
Converts list-style objects into Parameter lists
primarily used by the 'qi' methods. These list-style
objects may contain keys specifying: 'link' (the link
function of a statistical model), 'linkinv' (the
inverse-link function), 'family' (a object of 'family'
class used to specify the model's classification),
'alpha' (a vector of ancillary parameters, and
'simulations' (a vector of simulated draws from the
model's underlying distribution.
