invert

Object (coerced to) <code>mvp</code> form

Character vector of symbols to be replaced with their
 reciprocal; missing interpreted as replace all symbols

Given an <code>mvp</code> object, replace one or more symbols with their reciprocals

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'.
