Abstract
Morphological integration is correlation of parts, the integration of morphological traits or features that must function, grow, or be passed to offspring on as working units. Individual integrated units are modules, a group of traits that are highly correlated among themselves but only loosely correlated with traits in other modules. The study of integration and modularity was first developed by Olson and Miller (1958) and expanded on by Cheverud (1982), Zelditch (1988), Wagner (1995), Raff (1996), Klingenberg (2000), Mitteroecker (2007) and many others.
The basic component of studying modularity and integration is identifying packages of intercorrelated traits that behave independently of other such packages, whether through ontogeny, across individuals within a population, or during the course of evolution. This package performs a simple analysis of modularity on geometric morphometric landmark data.
This package accompanies the review by Goswami and Polly (2010). Users are referred to that paper for a discussion of the methods embedded in this package, including their strengths and weaknesses, and for elaboration of other methods that address broader problems.
