Coefficient Estimates of A Trained Angle-Based Classifier

Extract coefficient estimates from an abclass object.

Usage

# S3 method for abclass
coef(object, selection = c("cv_1se", "cv_min", "all"), ...)

object: An object of class abclass.
selection: An integer vector for the indices of solution path or a character value specifying how to select a particular set of coefficient estimates from the entire solution path. If the specified abclass object contains the cross-validation results, one may set selection to "cv_min" (or "cv_1se") for the estimates giving the smallest cross-validation error (or the set of estimates resulted from the largest lambda within one standard error of the smallest cross-validation error). The entire solution path will be returned in an array if selection = "all" or no cross-validation results are available in the specified abclass object.
...: Other arguments not used now.

A matrix representing the coefficient estimates or an array representing all the selected solutions.
