(longitude & latitude) Because i used the function clust of the clustTool package and it did'nt work at all: cl <- clust(dv,3,method="hclustAverage",distMethod="euclidean") thanks a lot Karine HEERAH Master 2 , océanographie et environnements marins Université Pierre et Marie Curie (Paris 6) _________________________________________________________________ Consultez gratuitement vos emails Orange, Gmail, Free, ... directement dans HOTMAIL !
