#Hi, I am trying to run an MRPP with community data (spp-site-matrix). I
use the following code:

mzbtaxa_mrpp <- mrpp(mzbdist,mzbsites$Site)

#mzbdist being a distance object (Bray-Curtis similarity matrix) derived
from my sqrt transformed community data set, created with function
'vegdist', mzbsites$Site refers to factors structuring my community.

#when I run this code, I get the following error message:

error in dmat[ind == x, ind == x] : (subscript) boolean index too long

#What does that mean? How can I solve this problem?

#thanks a lot for your help,

#Claudia
