mvp (version 1.0-8)

lose: Drop empty variables

Description

Convert an mvp object which is a pure constant into a scalar whose value is the coefficient of the empty term.

A few functions in the package (currently subs(), subsy()) take a lose argument that behaves much like the drop argument in base extraction.

Usage

# S3 method for mvp
lose(x)
