There's a bunch of different ways that R interfaces/bindings can go, apparently.
From what I can see, most straightforward way to interface with R would be to create a WorkSpace that can send WorkSpace input to an R interpreter and echo the output back to the workspace. You want something more than that, I assume. 


There's at least two Ruby interfaces to R that I could find. There's at 
least one Python interface.  My cursory reading from a few months ago 
didn't make clear the difference between the library bindings, the 
interfaces and the GUIs, so there's probably a lot of overlap.

Hi Lawson, I know from an experienced Java programmer, trying to make 
a binding to R, which is difficult to deal with particularities of 
connecting with R efficently (I could ask him for details if a student 
is interested in the project). I think R isn't comparable to what 
iGraph could provide, every day more studies results are presented in 
R and they are not necessarily described in network format. A 
front-end to R could be another interesting project idea though.

Cheers,

Hernán

    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
