For geographic distance, should use Vincenty distance. This looks awesome, I'd like to toy with this one. Precursor though: fetching records from EBI? |
Or, ideally, those and biom tables from the EMP database…?

All good ideas. Note that all code is used in the cookbooks needs to be in On Wed, Sep 24, 2014 at 8:36 AM, Rob Knight [email protected]

Right, with the EMP dataset we have control over both ends of the pipe so can make it easy (though of course it might be hard to make it easy...)

For example, we could look for associations between the geographic distribution of viruses and phylogeny. This could be done by computing euclidean distances between where (geographically) a particular viral strain is found, and the tip-to-tip distances between the viral strains in a phylogenetic tree, and then comparing the resulting matrices with a Mantel test.
Alternatively, in the macro-world, maybe something like beak length in some group of birds (but alternative suggestions would be great!). We could do this by computing a differences in beak length between the birds as a matrix, and compare that to the tip-to-tip distances from the tree using a Mantel test.
