Graphical and numerical analysis of spatial data with a GUI and R

Abstract

The paper is on the basis of DAS+R1, a package of where the emphasis is on a user friendly menu, a graphical user interface (GUI) enabling the call of different -functions which otherwise would afford a cumbersome typing in of possibly complicated commands for sophisticated methods of statistical data analysis. The package is still under development, nevertheless the actual state of the program system already enables the user to start easily with standard methods and continue with more complicated methods if the clickable commands already exist or by switching to the command line modus. We emphasize the repeatability of the generation of commands in several ways to intensify the speed of obtaining senseful results. A special view is put 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. We also give short illustrations on practical examples with geochemical, spatial data.
