Vegan: Diversity Plot, label points
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? Thanks in advance. Alejo
