and I assume you have seen Paul Gilbert's reply, giving "ex"
translations of a few idioms.

I think a few interested people should "sit together" (in cyberspace)
and try to improve on the current state.
I've included John Eaton, the author of GNU octave (the free
matlab `substitute'), because he certainly knows more about the
matlab "syntax" than any of us (and Kurt who once new a lot
about octave).
Probably everyone agrees that a Matlab -> R translation cannot
(and probably should not) be automated to full extent. On the
other hand, Paul Gilbert's "ex" script should be made into a
perl or python {or "octave" !?} script and could be enhanced
considerably, probably.
It could help matlab/octave users switch to R.
Another reason I'm interested to some extent is the
Statistics+Matlab community & software ("Wavelets", "Smoothers" etc)
where I would like us to get better connected to.
Robin> How about a specialist mailing list?
Not sure if this is needed and makes sense; I have already set up a dozen
R-SIG-* (R Special Interest Group in ****) mailing lists and
only a few are somewhat active.
But then it may make sense for a short time?
