There are a few R packages for deep learning, although I wouldn't say that they compare with Theano yet. There's darch (package for deep architectures and Restricted-Bolzmann-Machines) [1], deepnet [2] which is incorporated into caret which is nice, and gputools [3] which has some of the GPU operations found in Theano.
