Philippe Grosjean SciViews: an object-oriented abstraction layer to design GUIs on top of various calculation kernels ******************************************************************** SciViews aims to provide a unique, polymorph object-oriented interface (called "Plug") to different data analysis software like R, Octave, Scilab, Matlab, Splus, Ox, Mathematica,... It is thus possible to develop (Graphical) User Interfaces independently to the calculation kernel and adapt them easily to other systems. Moreover, the same GUI can possibly access several kernels simultaneously. A working prototype is developed in Visual Basic for Windows, but other implementations of this concept are possible. A plug to connect R is provided. Other plugs are in various stages of achievement. Several clients are also in development, including SciViews compatible clients for office programs (Excel and Word) and a versatile GUI with menus, toolbars, docking windows, a complete IDE and an integrated reporting system for generating rich-formatted texts with graphs called "Insighter".
