[R] dendrogram branches with different lty

[Romain Francois]

Hi Patrick,

You may want to try out my (highly experimental, so not on CRAN) package 
A2R.
http://addictedtor.free.fr/packages/A2R/A2R_0.0-3.tar.gz
2 dendro's are displayed on RGG, check 
http://addictedtor.free.fr/graphiques/search.php?q=dendrogram

You might also be interrested in Appendix B of Paul Murrel's book :
