hi, I'm trying to use pvclust function (pvclust package) to perform a cluster analysis and finding p-values for groups, however, i need to use the "squared euclidean distance" method instead of "euclidean distance" as distance matrix but it seems that the package only allows the last... any ideas how can I use squared distances instead of the simple ones in this function?
