Hi,
The thing that I wonder is whether it would be possible to embed Yacas
at a lower level than via the parser. E.g. the Tcl embedding has
Tcl_EvalObjEx() and friends, which operate on preparsed Tcl objects.
Using this instead of Tcl_Eval() gives some efficiency gain, but more
I forgot one API call, getting a potential error caused through
evaluating the object.
And I forgot one argument needed for evaluating, the pointer to the
environment.

Hi,
Maybe sending an R expression and getting an R expression back
for a 'suitable subset' of expressions is ok initially. Suitable could
cover 3 levels:
1) Mapping of names and standard functions, e.g. pi to Pi and
sin(x) to Sin(x) etc.
2) It would be nice if we can use threading of
where they are listed down the left hand side of the page. JGR,
and possibly
several others on the list, are written in Java. R can also be
accessed
directly online at:
http://www.math.montana.edu/Rweb/
and other sites.
And as of a week ago or so Yacas can also be accessed
I took the liberty of already adding the API to compose Yacas
expression trees,
executing them, and pulling them apart. This is just a preliminary
stab at it, we
can change it of course (removing void* for something else say). It
was relatively
little work.
You can get it from our cvs tree

I wonder how difficult it would be to translate expressions back and
forth from R to yacas in either R
or C++. And maybe strip 'In' and 'Out' like parts.
Not sure how generally this works but see my prior post:

I would use such a symbolic math package for R. I have dreamt of an
open-source solution with functionality similar to mathStatica.
http://www.mathstatica.com/ Is yacas the best system to consider? What
about Maxima http://maxima.sourceforge.net/, which is also GPL, or maybe
Axiom
