R help - Oct 2004 - plot.dendrogram and plot.hclust ZOOM into the height?

Hi,

I clustered a distance matrix and would like to draw it using 
plot.hclust or plot.dendrogram.
The dendrogram is not informative because I have a few extremely small 
dissimilarities in the distance matrix (e.g. 0), but most of the other 
distances are in the range 1e10+-5000.
I would like to show the tree only for the height of 1e10+-5000 but 
unfortunately their are no parameter like xlim,ylim in the function?
Are there other ways to ZOOM?

Any suggestions?

/E

Hi,

Just noted that
dendr2 <- cut(dendr1,h=10000)
plot(dendr2$upper)
Gives what I am looking for.
Sorry, Its quite late here.
