[R] Overlap of leaf labels

[David Winsemius]

I got an offlist response saying my advice was not correct, not  
surprising in the absence of a reproducible example on which to test.  
Looking at the help page, which seems the sensible place for anyone to  
start, we see that the second plotting example for dendrograms uses  
lab.cex and it need to be in a list offered to nodePar.

plot(dend1, nodePar = list(lab.cex = 0.3))

So I think my advice was correct up to the wider interpretation of  
"... or some such."
