Change label size of Cluster Dendrogram in R 3.01 -

Has anyone found an alternative solution for the obvious bug in R3, which is restricted to resize labels on the cluster dendrogram?

3.01 The following code was used to work just before the R. (prior to version 2.15) I think:

  Plot (Halstal, Labels = data [, 1], cx = 0.3)   
 There is no change in the size of the label in changing the  cex  argument.  
 
 
 Before you call  plot ()  using the function  cex  can set parameters  code>. For example: Examples of #define  (cx =) from the default label size plot (HC, XLAB = "XLAB", ylab = "hcl", "hcllst" (disturse), "ave" Plot (HC, XLAB = "", ylab = "" = "", main = "main", all = "") (2)  (0.3, m = c (5, 8, 4, 1)       / pre>
