[R-sig-eco] Interpreting large clusters

[Phil Novack-Gottshall]

Hi all,

I have a related question concerning cluster analysis of large data 
sets.  In my case, the matrix is reasonably small for R to work with, 
but I have so many species (~2000) that it is not possible to read 
labels on the resulting dendrogram.  I imagine that using an 
ordination is a preferable method in this case, but I was wondering 
whether anyone had any recommendations for producing a very large, 
but still readable dendrogram.  (I've tried increasing the window 
size and shrinking cex.text, but this still isn't sufficient.)

Cheers,
Phil
