allvars

Returns a character vector containing all the variables present in a
<code>mvp</code> object.
<pre><code>
&gt; (p &lt;- rmvp(3))
mvp object algebraically equal to
3 a^5 c^4 d^2 f^5 + 2 b^4 c^3 d^7 e^5 f^5 + b^9 c^8 f^5
&gt; allvars(p)
[1] "a" "b" "c" "d" "e" "f"
&gt; 
</code></pre>

symbolmath

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'.
