[BioC] Clustering method

[s0uchi02]

Hi all,

I have a question about analyzing Affymetrix data.
I used "affy" package to normalize Affymetrix data (RMA, MAS5.0, and Li and 
Wong methods).
I want to use hierarchical clustering method to cluster the normalized data 
according to experiments and genes.  What would be a good software to use?
I have used Dr. Eisen's "Cluster," but I got an error message.

Thank you in advance.
