Re: [R] RDA Triplot
Since I am doing an RDA with contraints I get this error message when trying to use biplot.rda: 'biplot.rda' not suitable for models with constraints Daniel 2010/11/26 Jari Oksanen [via R] ml-node+3060660-1324000642-57...@n4.nabble.comml-node%2b3060660-1324000642-57...@n4.nabble.com Danielwc daniel.carstensen at gmail.com writes: Im using the VEGAN package to do an RDA ordination.

[R] RDA Triplot
Hi Im using the VEGAN package to do an RDA ordination. In my plot I get my environmental scores as arrows/vectors, but my species scores as points. I would like to get the species scores as arrows as well. I tried the envfit function, and this creates arrows, but the lenght is not proportionate to the strengh of the correlation and the point is still there (so I both have point and arrow). fit - envfit(rdawal, dat.one, perm = 999, display = wa) ordiplot(rdawal, type = p) plot(fit, col = red, add = TRUE, scaling = 2) Is there not a way I can tell R to plot both environmental and species scores as arrows/vectors?

Re: [R] Nested variables
Hi. Yes I am trying to model such data, and i need R to know that Site is nested within Habitat. Do I use some kind of command before running the model (like factor() and so on) or do i write it in the model formula. If so, how?
