r - Suppress leaf labels in dendrograms -

I am not an expert in cluster analysis and thus I am not really familiar with all the special "contributions" packages, Just use the base routine, like I did for a quick example, which was told to produce me.

The problem is that there are about 7800 comments in my dataset, and so the leaf labels are very much multiplication and dislocation, so how can I stop plotting the labels? I'm guessing that some "foreign" parameters should be available through par which controls it?

 There you will see an explanation  labels  argument: " if  label = FALSE  no labels all    pre <>  > Hc & lt; - hclust (distr (USA rrests), "Away"
