Just wondering: did you try help(dendrogram) before sending an email
to r-help with subject "dendrogram"? The examples show you how to cut
a dendrogram at a specified height ...
If you want 10 leafs, you just have to get the height of the 9th
splitting (in element "height" of hclust objects).
help(cutree) might also be of interest ...
