vegan comes with a few vignettes, have a look at those. You can start with
this one:
http://cran.r-project.org/web/packages/vegan/vignettes/diversity-vegan.pdf
>From the vignette:
R> data(dune)
R> data(dune.taxon)
R> taxdis <- taxa2dist(dune.taxon, varstep=TRUE)
R> mod <- taxondive(dune, taxdis)
First few lines of dune.taxon:
Genus Family Order Subclass
Class
Belper Bellis Asteraceae Asterales Asterids
Dicots
Empnig Empetrum Empetraceae Ericales Asterids
Dicots
Junbuf Juncus Juncaceae Juncales Commelinids
Monocots
Junart Juncus Juncaceae Juncales Commelinids
Monocots
Airpra Aira Poaceae Poales Commelinids
Monocots
Have a look at dune.taxon. I hope that gets you started.
Cheers,
Roman
