This paper is on the basis of DAS+R, a package of R still under development using a graphical user interface which should ease the application of more or less sophisticated methods. It is heavily relying on Reimann, Filzmoser, Garrett, and Dutter (2008), for which it can represent a companion. The basis of the graphical user interface comes from the R Commander (see Fox, 2004). It uses Tcl/Tk programming tools. The emphasis is on the analysis of spatially depending uni- or multivariate data, particularly on problems of geochemical data. We describe in short the important features of data analysis in this field with realized functionalities with its clickable icons in DAS+R. Finally, we give a short illustration on a practical example. |
