Appendix

This file is an attempt to document the script, data, and functions (in the R graphics/statistics programming language) used in the analyses I carried out for the article 'Loosening the CLAMP', which is to be electronically published in {\it Palaeontologia Electronica} in 2006. All citations should refer to this article.

In addition to the article and this README file, there is a zip file new_supplement.zip which includes:

GregoryALL.txt
JacobsALL.txt
KowalskiALL.txt
my.dend.plot.R
pairstats.R
README.txt
Rscript_publication.txt
Wolfe173ALL.txt
Wolfe1993Data.txt

Please note - this material was replaced on 12/9/2013 due to loss of original files.

Like any software, this is a work-in-progress, so I recommend that anyone who intends to replicate my results contact me for newer and better-documented versions of these files. For anyone with modest familiarity with the R language, however, it should be possible to run the file Rscript.txt after making the necessary modifications for the platform on which it is to be run. In addition to setting a filepath in the indicated places, it will be necessary to source() the functions in the functions/ directory. All the data have been published before (in the cited publications) but are provided here for the first time in digital, machine-readable form. Note that the files were optically scanned or hand-typed and DO contain errors. The first part of the script file is devoted to laundering the data and cleaning some of these errors up, but any use of the data tables without running Rscript.txt should expect to find errors in the data. Nor is there any guarantee that my script has caught all the errors to be found....
