Convert .mat file to R-compliant file

I am in the need of converting a MATLAB .mat file in something that can be read from R. Do you know some tools that can be used to perform s开发者_如何学Gouch operation?

The .mat file contains cell matrices and struct matrices.

In recent releases, ".mat" files in Matlab are saved using the HDF5 format that you can read in R with the package hdf5

The R.matlab package provides a readMat function.

There is also a package named R.matlab that I didn't try but that seems available for Windows.
