Hi,
I am doing canonical discriminant analysis using candisc function from
the candisc package.
My input is a table of species distribution (columns = abundance of each
species in each sample) in samples that are split by categories (rows),
and I want to know whether each category is associated with a particular
set of species and their abundances.
I have 20 rows (samples) split into 6 categories, and 17 columns (species).
I am getting the following error message, which I don't understand:
> can<-candisc(mod, data=canIN)
Error in linear.hypothesis.mlm(mod, hyp.matrix.2, SSPE = SSPE, V = V, :
The error SSP matrix is apparently of deficient rank = 16 < 17
Does anyone has any experience in candisc?
