Re: [R-sig-eco] plotting capscale results using ordiplot in Vegan
Hi Colleen, Using capscale you can use the function plot.cca (use ?plot.cca to see all options) to make plots. If you use this: plot ( yourcapscaleresult, display=c(wa,bp)) you get the site scores (wa) and the constraining variables arrows (bp) biplot , but if you want the triplot, species scores are in a bigger scale and your sites collapse in the middle, so I would try to make the 2 biplots, plot ( yourcapscaleresult, display=c(wa,bp)) plot ( yourcapscaleresult, display=c(sp,bp)) hope this helps, Andrés ckellogg ctekell...@gmail.com escribió: Hi, I used capscale to examine relationships between relative species abundances at different sites with environmental variables. When I attempt to plot the results using ordiplot all of my site points are squished to the center of the biplot. I have tried changing the scaling and that only makes things worse. Is there anyway I can get the sites to spread out a bit in the ordination? Thanks so much!

Does: plot(, scaling = 3) where represents what ever you were including to plot the ordination in the first place help? Or is the problem that you have one (a few) rogue sample(s) and/or species?

Re: [R-sig-eco] plotting capscale results using ordiplot in Vegan
Right. The code. Sorry about that. This is what I used: plot(ANareabac_red.cap,choices=c(1,2),type='n',scaling=2) points(ANareabac_red.cap,choices=c(1,2),display='wa',pch=AN_info[,9],col=AN_info[,6],cex=1.5,scaling=2) I don't really have any outliers so I don't think that is the problem. I will give what Andres suggested (thanks!) a shot.

[R-sig-eco] plotting capscale results using ordiplot in Vegan
Hi, I used capscale to examine relationships between relative species abundances at different sites with environmental variables. When I attempt to plot the results using ordiplot all of my site points are squished to the center of the biplot. I have tried changing the scaling and that only makes things worse. Is there anyway I can get the sites to spread out a bit in the ordination? Thanks so much!
