Well, R is a language for statistics with it's own graphical tools
etc. This was the approach used by major statistic packages
a decade ago but it seems like all of them have been moving to
a more spreadsheet oriented approach in recent years.

I would like to see some day a package adds full math capabilities
to writer.. something like MathCAD. I doubt this project will head
that way but it would be a great tool to see in relation to TeX.

You should now better about the COIN license ;). The code was
originally from IBM. When it started it was strong thanks to the
Open Solver Interface that supports the top of the line
commercial solvers in the market.
CoinMP was a simple solution for the immediate problem but
we are not using the full advantages of the OSI interface.

For practical purposes though, the current CoinMP is more
than sufficient for the requirements of a basic OR course and
I suspect it will stay like that for the foreseeable future.

I see COIN-OR is starting to build some code around python
and I guess that's something we should examine in the future
since we are already carrying python.

There is a OOo extension for non-linear programming (partially
owned by Oracle) that was brought into LibreOffice. I personally
think bringing in such functionality that few people use is a
bad idea and just make the basic office suite bloated and
eventually unmanageable.
There are some really powerful libraries out there (fftw, taucs,
mumps ... ) that can be useful to make extensions but most
of them add the requirement of fortran to the build system.

Such tools can/should live as extensions.

No, Minitab was really innovative in offering a powerful
statistical environment with a spreadsheet interface at
a very competitive price (they raised the prices a lot
afterwards).

I guess I would mean the gnumeric approach. Keep it simple,
use existing tools.

Cheers,

Pedro.
