It seems that the coordinates that make up the border of Berlin (and the corresponding border of surrounding Brandenburg) are not positioned correctly. When I compute an outline from the coordinates, it is slightly but perceptibly off from my reference points. Translating and rotating (something like 1 or 2 degree) shifts the outline to the reference points.
You save them the same way you save linked files for most other web sites. This is a standard process, the gadm website doesn't seem to be any different from the usual way. Click on the links after using the download form:
Most common web browsers will produce a "save" dialog. If that doesn't work, right click on the link and choose "save target as".
You open the files using load("") from within R. That command will produce (or replace) an object called 'gadm', which has the shapefile elements inside. You can look at the structure by using str(gadm). You may need to install the package 'sp' first [install.packages("sp")].
