Installation instructions
Software
GNU R
First of all you need a working R installation, a recent version, like 2.7.0 is suggested. Please see the R homepage for installation instructions. R is available for Windows, MacOS X and Linux.
Note: the R homepage does not work properly with some browsers. Here is the direct link for the installation page, choose your operating system to proceed.
igraph package
Next, you'll need the igraph package. The easiest way to install it is starting R and then typing in the command
install.packages("igraph")
This downloads and installs igraph from one of the R archive network
servers. It may ask you to choose a mirror site, usually all mirrors
are up to date, but if you notice that you don't have the most
recent igraph version, please install igraph again using the mirror
in Austria. Typing in
library(help="igraph")will tell you your igraph version. The latest igraph version is shown in the upper right corner of the this page.
Data
Please download the judicial.csv and allcites.txt files from James Fowler's homepage. You can find more information about this data set on this homepage.
Please make sure that you can read in these files into R, e.g. by
using the read.csv() R function.
