[R] Mirror Image on Biplot Graphic

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.
