#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 [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
