I doubt it - there is no nmds command. Do you mean metaMDS() ?

Have a look at ?orditorp in vegan for an alternative approach, but yes you can use identify, but you have to capture the output of the plot call and use that in your identify call: require(vegan) data(varespec) mod <- cca(varespec) mod.plt <- plot(mod, display = "species", type = "p") identify(mod.plt) See ?identify.ordiplot for more info.
