Thanks a lot for your help (again) Mark.
I adapted your suggestion to my analysis.
But I'm getting and error when trying to apply the new values.
The error is:
Erro em scores(CAPpotiFTI)$species[, 2] <- scores(CAPpotiFTI)$species[, :
não foi posssível encontrar a função "scores<-"
Translating:
Error at scores(CAPpotiFTI)$species[, 2] <- scores(CAPpotiFTI)$species[,
:
it's not possible to find the function "scores<-"
Bellow how I applied the suggestion:
CAPpotiFTI<-CAPpotiFT
scores(CAPpotiFTI)$species[,2]<-scores(CAPpotiFTI)$species[,2]*-1
scores(CAPpotiFTI)$sites[,2]<-scores(CAPpotiFTI)$sites[,2]*-1
Any ideas? I'm trying similar things but without success.

Hi Rodrigo,
Sorry, that will not return a result (I use several different ordination
packages, in most of which this is possible). What you need to do with
vegan
is the following:
scores(mynew.cca)$species[, 2] <- scores(mynew.cca)$species[, 2] * -1
You will be able to do the rest.
Regards, Mark.

Hi Rodrigo,
I need to rotate on y axis the lines and symbols of constrained and
sites representation.
Easiest is to multiply the axis you want to invert by -1. Something like
the following, where my.cca is the orginal object and yax = obj[, 2]
(xax
being obj[, 1]). Obviously, copying isn't necessary.
mynew.cca <- my.cca
mynew.cca$scores$species[, 2] <- my.cca$scores$species[, 2] * -1
mynew.cca$scores$sites[, 2] <- my.cca$scores$sites[, 2] * -1
mynew.cca$scores$centroids[, 2] <- my.cca$scores$centroids[, 2] * -1
Regards, Mark.

He everybody,
Well I have a biplot CCA-like origined from plot.cca (vegan package). I
need to rotate on y axis the lines and symbols of constrained and sites
representation. If I do that on an image editor, I rotate everything,
including titles, axes labels and positions. I just need to rotate the
inner par and keep the variables names (constrained) and symbols in the
new positions but with the right direction.
So, is there on R a way to do that while creating the image?
Here is the code that generate the graphic.
plot.cca(CAPpotiFT,type='none',display=c('bp','sites'),main='Total
Fauna
Sites x Environment')
text.cca(CAPpotiFT,dis='cn',col='black',cex=0.6,lwd=0.5,lty='dotted')
points(ScoresCAPFT$sites[FatoresRep$BiofaciesBC=='1',],pch=21)
points(ScoresCAPFT$sites[FatoresRep$BiofaciesBC=='2',],pch=20)
points(ScoresCAPFT$sites[FatoresRep$BiofaciesBC=='3',],pch=22,bg='gray')
points(ScoresCAPFT$sites[FatoresRep$BiofaciesBC=='4',],pch=24)
points(ScoresCAPFT$sites[FatoresRep$BiofaciesBC=='5',],pch=24,bg='black')
points(ScoresCAPFT$sites[FatoresRep$BiofaciesBC=='6',],pch=25,bg='gray')
Thanks in advice.
