[BioC] How to hide or suppress note about ward method in clValid package?

[Kaj Chokeshaiusaha [guest]]

Dear R helpers,

I've used clValid package and use these command lines as following.
one2one.stability.hk <- clValid(obj=t(prep), nClust=c(2:4),  
	      clMethods = c("hierarchical", "diana",
			    "fanny","som","model"), 
	      validation = "stability",
	      maxitems = 13,
	      metric = "correlation", method = "ward", 
	      neighbSize = 10,
	      annotation = NULL,
	      GOcategory = "all",	      goTermFreq=0.05,dropEvidence=NULL,verbose=FALSE)

During the process, the message 
The "ward" method has been renamed to "ward.D"; note new"ward.D2"
keep showing unrelently. It is not the warnings and I can't manage to find a way to stop them. Would you please suggest me how to deal with the problem?

Best Regards,
Kaj
