Hi Serge!
I welcome very much this initiative. Something that I believe is important, is an pdf graph exporter (maybe based on EyeSee) and the various test distribution (e.g., CHI). The fact that these two are missing is exactly the reason why I use R and Numbers instead of Pharo.
I sincerely believe that Pharo can be an alternative to R and Maple. A bit more is needed from our side however.

Great initiative Serge, bravo.
Thank you Nicolas.
Yes Pharo could replace some parts of R/Maple/Matlab etc... but that's a tremendous work.
So please, small steps, bring up basic bricks first.
Yes i agree that we need to work in baby steps. Having a good infrastructure and developing a community is also important.
I have unpublished Smalltalk utility libraries for handling Euler (Cardan) angles, geodetic coordinates, geodesic and rhumb lines calculation on the ellispoid... For Euler angles, the main features are conversions to/from direction cosine matrices and quaternions, so it's more a problem of package delimitations and which matrix class to use, generic m x n, or specialised SO3...
Also, some higher level objects could be used (vector space, trihedron, etc...), but basic steps first.
Great ! Maybe you can help me as the second tutor ? Regards, -- Serge Stinckwich UMI UMMISCO 209 (IRD/UPMC), Hanoi, Vietnam Every DSL ends up being Smalltalk http://doesnotunderstand.org/
