For a Symmetric ring R of dimension n, R.hVariable is a function which assigns to each index 1\leq i\leq n the i-th complete symmetric function. If i is outside the given bounds, an error is returned.
i1 : R = symmetricRing(QQ,2,EHPVariables => (x,y,z));
i2 : R.hVariable 2
o2 = y
o2 : R
The object hVariable is a symbol.
