Extracts model coefficients from objects returned by PLN() and its variants
an R6 object with class PLNfit
type of parameter that should be extracted. Either "main" (default) for $$B$$ or "covariance" for $$\Sigma$$
additional parameters for S3 compatibility. Not used
A matrix of coefficients extracted from the PLNfit model.
