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.

Name: A binding to R
Level: Advanced

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:

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
