...sites", type = "p") with(firefactors, ordiellipse(com.mds, comm4, kind = "se", conf = 0.95, col = as.numeric(firefactors$comm4)) But that code also gives me blue ellipses. Finally, I'd like to label the ellipses. The only way I've found to do that is by using the ordispider() function. Is there any way to make ordispider draw no lines? I've tried with(firefactors, ordispider(com.mds, comm4, col = "green3", label = TRUE, lty = 3)) My two questions: 1. How do I make the ellipse color match the color of the points each ellipse represents? 2. How do I...

...39;m looking for.  If I go ahead and delete the column "row.names" from my data frames (i.e. removing it from turtles and turtles.env), I don't believe that the analysis is performed correctly. The two species differ significantly in most of their measurements, but the ordihull() and ordispider() commands show them overlapping almost completely. I think that I'm missing something pretty basic about inputting and formatting this data for this analysis. Can anyone offer a suggestion on where I'm going astray? I can send a copy of the data if anyone wants to look at it. Best wish...

Is there an option to draw concentration ellipses in biplots ? It seems really nice to summarize large number of points of each group. Cheers../ Murli
