The following works (at least in sage-4.4.4):
sage: R.<x,y,z> = QQ[]
sage: SF = SymmetricFunctions(QQ)
sage: SF.from_polynomial(x^2 + y^2 + z^2)
m[2]
sage: SF.from_polynomial(x^2 + y^2)
...
ValueError: x^2 + y^2 is not a symmetric polynomial
If someone wants to make a top level function like that suggested in the initial post, a design discussion should probably happen on sage.devel or sage.combinat.devel first.
I'm changing the component to combinatorics since that's where tickets related to symmetric functions usually live.
This is a little vague - should it also be for SR, not just polynomial rings? But it seems like a reasonable request on sage-support:
