o The new function parafit by Pierre Legendre tests for the
coevolution between hosts and parasites. It has a companion
- function, pcoa, that does principal coordinate decomposition. The
- latter has a biplot method.

o The new function lmorigin by Pierre Legendre performs multiple
regression through the origin with testing by permutation.
o The new function delta.plot does a delta plot following Holland et
al. (2002, Mol. Biol. Evol. 12:2051).
+ o The new function edges draws additional branches between any nodes

o add.scale.bar() has a new option 'ask' to draw interactively.
