-------- Original Message -------- Subject: modularity hypotheses for subsets of landmarks in a single configuration Date: Sun, 24 Jul 2011 14:30:44 -0400 From: John Denton <[email protected]> To: [email protected] Hi all, I am interested in tests using subsets within a single configuration, especially for modularity hypotheses (sensu Klingenberg [2009]), and comparing them to fits with two separate blocks. It appears that MorphoJ does not yet implement modularity hypotheses for subsets within a single configuration, and I am wondering if there is a package in R, or a script, that is available for such an analysis that includes an allometric correction before running. Also, I am also working a bit with fluctuating asymmetry, and have a question about its use with subsets in a single configuration--is the problem with running modularity analyses on a subset of the asymmetric component of a Procrustes ANOVA without reference to the total configuration alleviated if the the modularity hypothesis is run assessing subsets within the total configuration? Lastly, I'm wondering about methods for assessing digitization error (the error term in Procrustes ANOVA)--for example, is there a way to get these results by looking at the contributions to a matrix correlation between symmetric and asymmetric components by the diagonal and off-diagonal entries, instead of digitizing all samples multiple times? Thanks very much! ~John -- "ORGANIC LIFE beneath the shoreless waves Was born and nurs'd in ocean's pearly caves; First forms minute, unseen by spheric glass, Move on the mud, or pierce the watery mass; These, as successive generations bloom, New powers acquire and larger limbs assume; Whence countless groups of vegetation spring, And breathing realms of fin and feet and wing." ~Erasmus Darwin, The Temple of Nature Canto I.V
