distance matrix and hclustering
...) by using "as.matrix", i converted by data into a matrix. Now, I want to create a distance matrix. My data as shown above contains 364 rows and 4 columns. I have to create distance matrix based on the values of 2nd column. secondly, based on this distance matrix i would like to do "hclustering", to see which of the rivers have similar discharge patterns. more precisely, i need to see river(a,b,c,d) splitted in clusters with river having similar discharge patterns in one cluster. thnx in advanceeliza botto [[alternative HTML version deleted]]
