Workshop Program and Files:

Computer workshops are based on the software "R environment for statistical computing and graphics" - short "R". R is platform independent and is freely available from the R-project web-site.

An introduction to R for beginners will be given in a specific Workshop (03.10.2013). A detailed introduction is available from the R-project web-site.

For the time of the workshops a “fleet” of Macintosh Laptop Computers (Mac OS) will be available. Students are however encouraged to bring along their own portable computers (if available). We recommend you install R on your computer before the first workshop. The installation of the add-on packages needed for the ACWD workshops (see below) will also be explained during the workshop on 03.10.2013.

Additional Packages:

Additional software and datasets are needed for the workshops. They are provided as additional packages (adding functionality to the R standard installation). To make your R installation ready for the workshops follow these steps:

1) Install the following packages from the R-website via the "Package Installer" command in R. These are contributed packages generally available from the R-website.

fitdistrplus, maps, mapproj, mapdata
2) Download the following packages (without unzipping) from the present website (using your browser). Store them on your disk, and finally install them into R using the "Package Installer - Local Source Package" command in your R. (The order of installation should be as the packs are listed.)

Packages for Linux and Mac:
trend_1.5.1, gevXgpd_1.3.7, geocors_1.2.8, plotmap_2.3.7, pcaXcca_1.4.1, ACWD_2.0.0


Packages for Windows:
trend_1.5.1, gevXgpd_1.3.7, geocors_1.2.8, plotmap_2.3.7, pcaXcca_1.4.1, ACWD_2.0.0
