This function provides estimated
coefficients from a fitted "`abess`

" object.

```
# S3 method for abess
coef(object, support.size = NULL, sparse = TRUE, ...)
```

- object
An "

`abess`

" project.- support.size
An integer vector specifies the coefficient fitted at given

`support.size`

. If`support.size = NULL`

, then all coefficients would be returned. Default:`support.size = NULL`

.- sparse
A logical value, specifying whether the coefficients should be presented as sparse matrix or not. Default:

`sparse = TRUE`

.- ...
Other arguments.

A coefficient matrix when fitting an univariate model including gaussian, binomial, poisson, and cox; otherwise, a list containing coefficient matrices. For a coefficient matrix, each row is a variable, and each column is a support size.
