Hello all,

I am doing a CAP (or dbRDA) in vegan, using the function "capscale", where
the response is a dissimilarity matrix (Sorensen's distance index) and the
explanatory matrix consists of 19 variables. The code runs apparently fine,
but the species scores appear as NA (site scores are properly given).

Does anyone knows what might be the problem?

Thanks,

Duarte
