lose

lose.mvp

drop

Convert an <code>mvp</code> 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 <code>subs()</code>, <code>subsy()</code>)
take a <code>lose</code> argument that behaves much like the <code>drop</code>
argument in base extraction.

Fast manipulation of symbolic multivariate polynomials
using the 'Map' class of the Standard Template Library. The package
uses print and coercion methods from the 'mpoly' package (Kahle
2013, "Multivariate polynomials in R", The R Journal, 5(1):162), but
offers speed improvements. It is comparable in speed to the 'spray'
package for sparse arrays, but retains the symbolic benefits of
'mpoly'. To cite the package in publications, use Hankin 2022
<doi:10.48550/ARXIV.2210.15991>. Uses 'disordR' discipline.
