A binding to R would be relatively trivial, I think. A binding to
iGraph would be a bit more challenging and would allow for things like
using Connectors to directly create/define iGraph data structures and
use iGraph's API to modify their behavior.

Description
With the increased popularity of high-level statistical programming
language and environments for data analysis like R, a way to interface
this package is becoming a must have for Smalltalk, since it
implements complex and unrivalled statistical techniques for data
manipulation and presentation, like Analysis of Variance, Covariance,
Time Series, Generalized Linear Models, Additive Models, Non-linear
Regressions, Tree Models, Multivariate Statistics, etc. besides the
many mathematical functions, which are used in fields from economics
to medicine and engineering. It is estimated that R posseses about 2
million of users worldwide and more than 2000 add-ons and increasing
everyday through repositories like CRAN and Crantastic.org
Technical Details
The student should know or be motivated to learn statistics with the R
environment and language, and its fundamental workflow: importing and
preparing the data, and finally running the analysis, and presenting
the results. Dealing with R sessions and presentation of results (like
vectors and plots) will be challenging too.
Benefits to the Student
The student will gain invaluable experience from two complementary
environments, and his experience with the interface technology choosed
will be useful for the many projects where Smalltalk needs help from
external systems.
Benefits to the Community
The goal of this project is to build a wrapper to interface R, an open
source statistical programming language, providing a whole range of
missing functionality to Smalltalk. This binding could complement the
R environment where a general programming environment is needed,
attracting many statisticians, and will open Smalltalk to
domain-specific areas as diverse as Clinical Trials, Finance and
Machine Learning.

Dear Smalltalkers,
We just submitted the application to this year GSoC, now let we wait
with fingers crossed for Google until next Friday to decide. I
think we
have quite some chance, specially because we collected and very well
described 22 project ideas:
http://gsoc2012.esug.org/ideas
There is still a time for ideas, so if someone has still half finished
one, please finish and publish it. Also authors of ideas please
check if
your idea is put correctly on above page.
Best regards
Janko and Carla
