Because the data types of R and Octave are not fully equivalent (only
matrices up to 2 dims, no "factors" in Octave ...), you have to limit yourself
to a subset of the types or have to invent a translation mechanism.  For quick
reading of Octave (ASCII) data into R, read.table() with its options may be
sufficient.  Look for scan() and read.fwf(), too.
