Looking for help for R

March 6, 2010

As you probably all know, Cantor currently has 4 available Backends: Sage, Maxima, KAlgebra and R. While the first 2 are in pretty good shape, as they are what I mainly use, and KAlgebra is maintained by apol, the R backend of Cantor is still lagging behind.

It started out as an afternoon hacking rush, and hasn’t changed much ever since. Mostly because I don’t have much usage for it at the moment.

While it does support the basics (running a command and showing the results) it does miss a lot of the nice features, Cantor is offering, like Tab-Completion, Syntax Highlighting or Assistant dialogs.

The feedback I got for Cantor so far tells that quite some people want to use R as backend, so I feel a bit bad that it is only a second class citizen in the family.

So I’m looking out for some help making the R support as good as the other backends (or even better). If you are a developer with needs for a nice statistical app and looking for a new challenge, please drop me a mail, and join the Cantor development.

Introducing Cantor

October 20, 2009

This post comes a bit late, so some of you may already have heard the news: KDE Edu will ship a new application in 4.4: Cantor*.

Cantor is an application that lets you use your favorite mathematical applications from within a nice KDE-integrated Worksheet Interface, and offers assistant dialogs for commonly used functions like solving equations or integrating/differentiating a function. It currently has support for three Backends Sage, Maxima and R.

It is aimed to fill the gap, most free software math packages have, compared to proprietary systems: an intuitive to use graphical interface.

Some of it’s most important features are:

  • View of plotting results inside the worksheet or in a separate window
  • GetHotNewStuff integration to upload or download example worksheets
  • Typesetting of mathematical formulas using LaTeX
  • Backend aware syntax highlighting
  • Tab completion and integrated syntax help

This is how it looks:
