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?
