I am beginning to work with the 'ape' package in R, and have run into some trouble. I generated a UPGMA tree based on DNA sequence distance in Paup* and read it into R, where it became an object of class "phylo". However, I need it to be classified as a "dendrogram" for my purposes (to use it to order the layout of a heatmap). I get an error using as.hclust.phylo because the tree is not ultrametric. Is there no way to convert a non-ultrametric tree of class "phylo" into a "dendrogram"?
