Dear all, I have two species by site matrices that I?d like to test for community concordance. All the needed previous steps to use the protest function in the vegan package are OK. But when I run the following command: protest(scordcacomA, scordcacomB, scores = "sites", permutations = 10000)->comAcomB I receive that error message: Error in crospord(X, Y), arguments not compatible.
Usually this error means that arguments are not compatible. Normally they have different numbers of rows. What do you get from dim(scores(scordcacomA, dis = "sit")) and dim(scores(scordcacomB, dis="sit"))? Cheers, Jari Oksanen
