I'm using the CDNA Library for classification of vegetation communities. My original data has 25000 records and I cut the tree back to 250 classes. I wish to write this cutdown tree to a text based matrix that I can load into R for use in a hclust class, particularly to generate a dendrogram in R. Any tips on where I may obtain some code snippets or a decent explanation as to how I may approach this problem.

Many thanks in advance...
