Hi Chris,
To get a single value you might need something like a Mantel test, available in
both ecodist and vegan. That test is a permutation test of significance of the
correlation between two distance matrices.

Hey Josh (and everyone),
My apologies, let me be more specific. I have two sets of XY coordinates in
Cartesian space. I would like to compute a correlation between the two sets.
For example, let's say I have two N X 2 matrices, with the first column being
the X coordinate, the second column bei
Hi Chris,
As Jeff mentioned, it is hard to tell what you want (correlations
between sets of coordinates could mean many things it seems like to
me), but here is something that perhaps helps:
## some data (usually nice if you provide this rather than us having
to make something up)
d1 <- cbind(x <
Isn't that one of the main things base R is used for?
Maybe your question is not specific enough. Can you provide some sample data
and your best estimate of what the result should look like?
The Posting Guide mentioned below could help you elicit more effective answers.

Hello r world,
Does anyone know a function or package that can compute correlations between
sets of XY coordinates?
Thanks in advance for your help,
Chris
