In this paper we characterize those functions f of the real line to itself such that the nonlinear superposition operator T f defined by T f [g]:= fog maps the Holder-Zygmund space C s (R n ) to itself, is continuous, and is r times continuously differentiable. Our characterizations cover all cases in which s is real and s > 0, and seem to be novel when s > 0 is an integer.
