  We show how so-called Yang-Baxter (YB) deformations of sigma models, based on
an R-matrix solving the classical Yang-Baxter equation (CYBE), give rise to
marginal current-current deformations when applied to the Wess-Zumino-Witten
(WZW) model. For non-compact groups these marginal deformations are more
general than the ones usually considered, since they can involve a non-abelian
current subalgebra. We classify such deformations of the AdS(3) x S(3) string.
