Hello again listers,
I've had no problems rotating metaMDS ordindation with 2 axes to a vector of
interest. Unfortunately, for my particular dataset stress is > 0.20 for 2
axes.  I'm wondering if it's possible to rotate the first axis for an
ordination with 3 axes somehow, maybe by specifying a 2 by n matrix? That
doesn't seem to work, though. Does anyone have any thoughts on how to
accomplish this (or whether it's a legitimate goal)?
Thanks, Erik

################### EXAMPLE
library(vegan)
data(varespec); data(varechem)
ord1 <- metaMDS(varespec, k = 2)
ord2 <- metaMDSrotate(ord1, varechem$pH) # no problems here

ord3 <- metaMDS(varespec, k = 3)
ord4 <- metaMDSrotate(ord3, varechem$pH) # not "conformable"
ord5 <- metaMDSrotate(ord3, cbind(varechem$pH, varechem$Humdepth)) # doesn't
work with matrix
