Hello r-helpers

I have a correlation matrix (either pearson or spearman) of 41 variables and i want to use it to construct a tree with agnes command (instead of using the distances). My problem is that at the height of the tree i see negative scaling also which is not desired. Is there any r-command that uses as a distance method the correlation estimates instead of distances (distances=dissimilarities, correlations=simmilarities) so that the height of the tree will be between 0 (zero) and 1 (one). Or simply, is there a way to transform the correlations in a proper way and to use the agnes command for example so that the height of the tree will be between 0 and 1?Thank you very much.
