Development of a Data Analysis System in R, with Graphical Interface

The computer program system R already offers extremely many powerful data analysis tools. The development of a general graphical user interface is still at the beginning (Fox, 2004). We discuss the historical entrance of an older data analysis system (DAS) with many ``new'' and powerful features in an R-package. This is designed for graphically oriented analysis with special emphasis on geochemical data. Practical examples from the Kola project are illustrated.
