Dear All, It's Eszter again from Hungary. I could not solve my problem form yesterday, so I still have to ask your help.
I have a binary dataset of vegetation samples and species as a comma separated file. I would like to calculate the Jaccard distance of the dataset. I have the following error message: Error in rowSums(x, prod(dn), p, na.rm) : 'x' must be numeric In addition: Warning message: results may be meaningless because input data have negative entries in: vegdist(t2, method = "jaccard", binary = FALSE, diag = FALSE, Do you have any idea what can be the problem? I have only 0 and 1 in the dataset. Thank you very much! All the best: Eszter _______________________________________________________________________ KGFB 2006 - Garantáltan a legjobb ár!
