I'm looking for a collaborator with strong R debugging skills to work on a project involving symmetric permutations. Should have interest in permutation/randomization methods. Please reply directly to me and not to the list. Phillip Good for background, see http://tbf.coe.wayne.edu/jmasm/vol1_no2.pdf pages 243-47, or http://mysite.verizon.net/res7sf1o/subgroups.htm
