These analyses were designed for use with vegetation data in the form of a matrix with sites as rows and species as columns, and containing some measure of abundance for each species at each site. If you don't have an original data frame, that is, your data come only in the form of distances, you will need a different implementation of constrained ordination. Alternately, you could possibly modify the function to skip the species scores step.
