Dear All, I wrote a function for cluster analysis to compute cophenetic correlations between dissimilarity matrices (using the VEGAN library) and cluster analyses of every possible clustering algorithm (SEE ATTACHED) http://old.nabble.com/file/p26288610/cor.coef.R cor.coef.R . As it is now, it is extremely long, and for the future I was hoping to find a more efficient way of doing this sort of thing.
To give you an outline of the function, first I create the dissimiarity matrices using all possible methods in the VEGAN command "vegdist", then create the clusters using all possible algorithms in "hclust" and the dissimilarity matrices I crated, then create a table, and in one column, list all combinations, and in the other, compute and put the cophenetic correlation. Any help would be appreciated! I'm pretty new to writing my own functions but I see great time-saving potential. Thanks!
