envfit output (vegan package) - not sure what it means
...e output of
a function that was recommended to me.
I've used the *envfit *function in the vegan package to plot vectors of four
climate variables onto a species matrix ordination. The output indicates
that only a single variable (mean_temp) is significant:

Vegan plotting- color help
I have looked all over the internet for being able to color sites
differently in a plot of an MDS (metaMDS)- I would like to color the
different sites in the ordination plot (plot or ordiplot). I have set
the matrix up so that my site code is 1 .... 296 (first column). is
there a way to make 1-23 blue, 24-40 red etc.
thanks
Stephen

labeling loading vectors in vegan
Hello,
I am using vegan to do an NMDS plot and I would like to suppress the labels
for the loading vectors. Is this possible? Alternatively, how can I avoid
overlap?
Many thanks for the help.
Example code:
#perform NMDS using metaMDS() function
spe.nmds<-metaMDS(data, distance='bray',k=2 , engine = "isoMDS",
autotransform=F, trymax=1000)
#calculate the loading (i.e.,
