R: Extract one model from a fitted "'abess'" object.

extract {abess}

R Documentation

Extract one model from a fitted "`abess`" object.

Extract the fixed-support-size model's information such as the selected predictors, coefficient estimation, and so on.

extract(object, support.size = NULL, ...)

## S3 method for class 'abess'
extract(object, support.size = NULL, ...)

`object`	An "`abess`" project.
`support.size`	An integer value specifies the model size fitted at given `support.size`. If `support.size = NULL`, then the model with the best tuning value would be returned. Default: `support.size = NULL`.
`...`	Other arguments.

A list object including the following components:

`beta`	A `p`-by-1 matrix of sparse matrix, stored in column format.
`intercept`	The fitted intercept value.
`support.size`	The `support.size` used in the function.
`support.beta`	The `support.size`-length vector of fitted coefficients on the support set.
`support.vars`	The character vector gives variables in the support set.
`tune.value`	The tuning value of the model.
`dev`	The deviance of the model.
