However, as most trees are currently created using hclust, all examples have binary trees. E.g., example(dendrogram) d3e[[3]]=d3e attr(d3e,"members")=14 str(d3e) creates a tree with three branches in the root node (not all attributes are correct after that brute force operation, so plots will not look as nice as possible).
