[R] Correlation matrices

[Ben Bolker]

  Do you have any leads on statistical methods for solving this problem
(independent of implementation in a particular system)? This doesn't seem
like an R problem as much as a more general statistical problem.  Also,
what do you mean by "better"?  More powerful?  Incorporating more
information about your particular problem?  I'm not aware (although I'm
admittedly pretty ignorant) of any really good general alternatives to
Mantel's test, given the breadth of possible applications. You could try
asking in sci.stat.math or sci.stat.consult (?).

  I guess the only R-specific issue is that if you did have an alternative
in mind it would quite probably be a permutation test of some sort, which
would mean that either efficient R-coding or coding the test in C or
FORTRAN and interfacing to R would be a good idea.
