This is actually a question regarding R but I think some of you might have encounterd that problem? How can I change the font of the labels in a plclust statement? For example I want to label my data with numbers, but with 56 numbers they are already overlapping and thus you can not easily distinguish them? Is there a possiblity to set parameters, which avoid this problem? Thanks plclust(sample.clusters,labels=1:56,main="Hierarch. Cl. Gene")
