ecodist (MRM) error message

Alfredo,

I'd be happy to try to help, but need rather more information.
What version of R, ecodist? What OS?

What do your data look like - str() is very helpful in this regard,
or possibly summary(as.vector(Dx)) and summary(as.vector(Dy)).
What are Dx and Dy? How were the dissimilarities calculated?

Can you provide a reproducible example so that I can see the error
for myself?

With only what you have provided here, there's nothing I or anyone else
can do to assist you.

Hi Everyone,

MRM is returning what seems to be a matrix singularity error:

Error in solve.default(XX) :
?system is computationally singular: reciprocal condition number =
1.88323e-86

when running MRM(Dy~exp(Dx)).

I would appreciate it if anyone could help me around this.

Thanks,

A
