Plots of the data.

To install all the R library packages used by the code type:

source("install.R")

at the R command line (if binaries are not available for your system, then they will be built from source and any dependencies will not automatically be detected).

All programs read the file: ESEUR_config.r. Put a copy of this file in what R considers to be its home directory.

The ESEUR_dir environment variable can be set to the directory containing these files.

This file sets the variable ESEUR_dir to contain the base directory containing all the code+data. The default value is R's home directory.

The .R files are a superset of what appear in the book. If some data was analyzed and I thought it useful, but could not find a place for it in the book, it was put in a misc/ directory (some files may not have been moved).

The data has been compressed to stay under Github size limits and reduce download time. You might find some filename strings are missing a .xz.
