matel.rtest accepts both Euclidean and non Euclidean matrices. If both
distance matrices are Euclidean, then a faster algorithm is used to
speed up the permutation procedure.
You can also use mantel.randtest which is exactly similar to rtest but
faster as computation are in C.

Hi,
For the Mantel test, your matrices do not need to be Euclidean, but they
do need to be symmetric. You could write a similar test that does not
require a symmetric matrix, though.

Hi List,
I would like to compare two (confusion) matrices. I ended up with the
ade4 mantel.rtest function as my best option. However it seems that my
data is non-euclidean in nature (is.euclid gives a FALSE). I attached
both matrices at the end of the document.
Are there any tools to tran
