Test modularity hypothesis
Tests modularity hypothesis using cor.matrix matrix and trait groupings
TestModularity( cor.matrix, modularity.hypot, permutations = 1000, MHI = FALSE, ..., landmark.dim = NULL, withinLandmark = FALSE )
cor.matrix |
Correlation matrix |
modularity.hypot |
Matrix of hypothesis. Each line represents a trait and each column a module. if modularity.hypot[i,j] == 1, trait i is in module j. |
permutations |
Number of permutations, to be passed to MantelModTest |
MHI |
Indicates if test should use Modularity Hypothesis Index instead of AVG Ratio |
... |
aditional arguments passed to MantelModTest |
landmark.dim |
Used if permutations should be performed mantaining landmark structure in geometric morphomotric data. Either 2 for 2d data or 3 for 3d data. Default is NULL for non geometric morphomotric data. |
withinLandmark |
Logical. If TRUE within-landmark correlations are used in the calculation of matrix correlation. Only used if landmark.dim is passed, default is FALSE. |
Returns mantel correlation and associated probability for each modularity hypothesis, along with AVG+, AVG-, AVG Ratio for each module. A total hypothesis combining all hypotesis is also tested.
