In projpred: Projection Predictive Feature Selection

Retrieve the full-data solution path from a varsel() or cv_varsel() run or the predictor combination from a project() run

Description

The solution_terms.vsel() method retrieves the solution path from a full-data search (vsel objects are returned by varsel() or cv_varsel()). The solution_terms.projection() method retrieves the predictor combination onto which a projection was performed (projection objects are returned by project(), possibly as elements of a list). Both methods (and hence also the solution_terms() generic) are deprecated and will be removed in a future release. Please use ranking() instead of solution_terms.vsel() (ranking()'s output element fulldata contains the full-data predictor ranking that is extracted by solution_terms.vsel(); ranking()'s output element foldwise contains the fold-wise predictor rankings—if available—which were previously not accessible via a built-in function) and predictor_terms() instead of solution_terms.projection().

Usage

solution_terms(object, ...)

## S3 method for class 'vsel'
solution_terms(object, ...)

## S3 method for class 'projection'
solution_terms(object, ...)

Arguments

object	The object from which to retrieve the predictor terms. Possible classes may be inferred from the names of the corresponding methods (see also the description).
...	Currently ignored.

Value

A character vector of predictor terms.
