I'm trying to place labels so as to avoid covering points (and other labels) in an ordination plot. I've been trying to use orditkplot() for this purpose, but get an error message, even when I try to replicate the example: >require("vegan") >data(varespec) > ord <- cca(varespec) > orditkplot(ord, mar = c(4,4,1,1)+.1, font=3) Error in structure(.External(.C_dotTclObjv, objv), class = "tclObj")...

Hi, I?m doing cca for a community data set in R and I have made a biplot for my data. Otherwise everything seems to be allright but the biplot is so messy I can?t read it well enough or publish it. I would like to get the row numbers out of the plot: I want the species position and the environmental variables in it as vectors but not the station numbers. How do I get them out? I have a raw

Dear experts, I would like to be able to interactively (if possible, with mouse and clik) edit point labels in graphs, particularly in multivariate graphs, such as the biplots you get after a correspondence analysis (with, for example, package ca), where labels tend to overlap. The graph aspect ratio is relevant (it needs to be mantained). And I'm working with Windows XP. In this kind of
