It is easier to exchange files between R, Matlab, Octave, Scilab, etc.
by using the ASCII format, not a specialized or proprietary one.

For transferring vector a from Octave to R:

O:  save -ascii a.txt a                 in Octave
R:  a <- scan("a.txt")                  in R

For transferring vector a from R to Octave:

R:  write(a, "a.txt")
O:  a = load("-ascii", "a.txt");

If you'd prefer a fancier format, "HDF5" could be nice (not Mac OSX):

R:  library(hdf5)
    hdf5save("a.txt", a)
O:  a = load("-hdf5", "a.txt");
