  2. Book: Applied Statistical Data Analysis DAS+R a companion of this book (Wiley, 2008). Emphasis: • Spatial Data • Strong Graphical Tools • Data from Geochemistry • Little Mathematics • Provided Software: 1 DAS+R

  3. DAS+R (future package of R) • Basis: DAS, (all) functions of R, Tcl/Tk • Emphasis: – easy to use (e.g. Rcommander) – fast reproducibility (with small changes) of the results – interactive definition of subsets (numerically and graphi- cally) – strong interaction between statistical data and spatial information – graphical analysis 2

  45. Summary • DAS+R is user friendly • enables to construct complicated R-commands via the GUI • high repeatability (fast prototyping) • using of subsets (of variables/observations) • emphasis on graphical analysis. • Finally: Embedding of new functions should not be diffi- cult!!!! 44

  46. Outlook To do: • Complete intended methodology • Enter all the subsets functionalities in the procedures where applicable • Remove most of the bugs • Fill all help buttons • Submit the package to CRAN. 45
