Dear all,
linked to MRPP in Vegan there is a really nice function (meandist) which calculates a matrix of mean of distance, based on a grouping factor, from matrices of dissimilarity. I was wondering if there is an equivalent function calculating the standard deviation instead of the mean distance or if anyone has an idea how to do it.
thanks a lot!
