[R-sig-eco] labels to a varpart diagram

[Emili Garcia-Berthou]

Dear list members:

Does anybody know how to add labels to the sets/circles of a "varpart"
diagram?

E.g., how to add labels to the three circles obtained with:

data(mite)
data(mite.env)
data(mite.pcnm)
mod <- varpart(mite, ~ SubsDens + WatrCont, ~ Substrate + Shrub + Topo,
   mite.pcnm, data=mite.env, transfo="hel")
plot(mod)
mtext("Variation partitioning")

The standard "text" or "legend" functions used for plots do not work
presumably because it is a "varpart" object.

Thank you in advance!
