Dear List, I can'f figure how to add point labels in the next plot (example from ?taxondive help page): library(vegan) data(dune) data(dune.taxon) taxdis <- taxa2dist(dune.taxon, varstep=TRUE) mod <- taxondive(dune, taxdis) plot(mod) The points in this plot are diversity values of single sites, and I'd like to add a label to each one. The plot command don't accept a "label" argument. Any tip?
A couple of options:
with(mod, text(Species, Dplus, label = rownames(dune),
pos = 2, cex = 0.7))
fiddle with pos - see ?text for details.
Another option is
with(mod, identify(Species, Dplus, label = rownames(dune), cex = 0.9))
where you now click around the points you want to label. See ?identify
for further details.
