dcov
(Package: groc) :
Distance covariance matrix.
Compute the distance covariance measure of Szekely, Rizzo, and Bakirov (2007) between two samples. Warning: Only valid to compute the distance covariance for two random variables X and Y. This means that X and Y cannot be random Vectors. If this is the case, consider the package energy.
