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.

Name: CSS Template System Level: Easy / Intermediate Possible mentor: HernÃ¡n Morales Durand Possible second mentor: ? Description Cascading Style Sheets (CSS) is a technology which allows personalized presentation styles of document contents. It is based in textual source code which has influence on the visual style and presentation of HTML and XML documents. This includes ways of assigning layout and style properties, such as font types and sizes, for different types of document components when they are presented. As having a long adoption rate from specification (CSS 1 : 1996, CSS 2 : 1998) to be fully supported by web browsers (2000 & 2006 for CSS2) it is predictable that CSS 3 modules like Backgrounds and Colors, Media Queries, and Multi-column Layout will come in no short time from now (2012), although many web sites today use CSS heavily. Through the years, the need for high-level presentation objects like grids and common layouts, leaded to the creation of CSS libraries called frameworks ( http://en.wikipedia.org/wiki/CSS_frameworks) to help web programmers in composing more attractive web sites in a rapid way. Technical Details The objective is to complete an initial CSS framework in Smalltalk (Phantasia http://www.squeaksource.com/Phantasia) with CSS Template objects. Phantasia avoids to learn CSS syntax, and with proper completion could obtain a rich object model of CSS objects beyond the specification limits, suitable to edition through Smalltalk code. High-level template objects could include navigational ones like lists, menus, or palettes, useful in wizards. Presentational objects like template layouts, which are already implemented by external CSS libraries like Blueprint, and scale to whole CSS templates including reports, galleries, etc. The model should be independent of web framework so it could be re-used in Seaside, Aida, Iliad or other future web frameworks. Benefits to the Student The student will learn how to build and extend a model for a limited textual technology (CSS), from the low level objects like CSS functions to high level objects like Positioners. The student could apply the results of his work to several popular Smalltalk web frameworks. Benefits to the Community The Smalltalk community working with web technologies will be tremendously favoured by having ready-made CSS objects to incorporate easily in their web applications. 2012/3/9 Janko MivÅ¡ek <janko.mivsek(a)eranova.si> > 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.

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, HernÃ¡n 2012/3/9 Lawson English <lenglish5(a)cox.net> > A binding to R would be relatively trivial, I think.

I guess using Connectors to provide a GUI on top of an R binding would be more impressive to most R users, but its nowhere near as difficult as doing it in Python or Ruby (been contemplating how to do it for about a 6 months now -just haven't actually coded anything). http://web.kuicr.kyoto-u.ac.jp/~alexg/rsruby/manual.pdf L.

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 Possible mentor: ? Possible second mentor: ? 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. 2012/3/9 Janko MivÅ¡ek <janko.mivsek(a)eranova.si> > 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.
