Hi Christoph,
There was some discussion following a similar question a year ago:
The question:

The threads:
https://stat.ethz.ch/pipermail/r-sig-phylo/2008-April/thread.html#35
I'll be interested to hear what approach you take, so let us (or me anyway)
know.

Quoting Christoph Heibl <christoph.he...@gmx.net>:
A question to the comparative method gurus:
I have a phylogeny for a group of plants that repeatedly evolved
annuality from perennial ancestors. For each tip in the tree I have
characterized the climatic tolerances (e.g. temperature,
precipitation, ...)
.
I would like to assess if there is a significant correlation between
life cycle (discrete) and climate variables (continuous).
I am not sure how to start with this and would appreciate your opinion!
Regards,
Christoph
