Hi Rodrigo,
Sorry again: the structure vegan uses is quite co
ow how I applied the suggestion:

>> scores(CAPpotiFTI)$sites[,2]<-scores(CAPpotiFTI)$sites[,2]*-1

cies[,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.

Hi Rodrigo,

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
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 t
