### Arguments

`object` | an R6 object with class `PLNfit`
`type` | type of parameter that should be extracted. Either "main" (default) for Θ or "covariance" for Σ
`...` | additional parameters for S3 compatibility. Not used

### Value

A matrix of coefficients extracted from the PLNfit model.

### Examples

    data(trichoptera)
    trichoptera <- prepare_data(trichoptera$Abundance, trichoptera$Covariate)
    myPLN <- PLN(Abundance ~ 1 + offset(log(Offset)), data = trichoptera)
    coef(myPLN) ## Theta
    coef(myPLN, type = "covariance") ## Sigma
