x: The data input. Can be one of two structures: (1) A data matrix where rows correspond to elements and columns correspond to features (a single numeric feature can be passed as a vector). (2) An N x N matrix dissimilarity matrix; can be an object of class dist (e.g., returned by dist or as.dist) or a matrix where the entries of the upper and lower triangular matrix represent the pairwise dissimilarities.
groups: A grouping vector of length N, usually the output of matching.
Returns
The diversity (sum of distances) by group.
Details
Plots the sum of pairwise distances by group.
Examples
