Hello everyone ... I just wanted to know what are the different cluster methods available in bioconductor apart from K-means and hierarchical clustering and what are the libraries can be used for the same purpose .... I am using affymetrix data Thanks Rohit -- Rohit Farmer M.Tech Bioinformatics Department of Computational Biology and Bioinformatics Jacob School of Biengineering and Biotechnology Sam Higginbottom Institute of Agriculture, Technology and Sciences (Formerly known as Allahabad Agricultural Institute - Deemed University) Allahabad, UP, INDIA - 211 007 Ph.

To find out what is available on your system (installed), try: help.search('clustering') If that isn't satisfying, try: RSiteSearch('clustering',restrict='functions',matchesPerPage=100) This list will include functions in packages perhaps not even installed locally. You can then install and test as you see fit. The vast majority of these clustering methods are not specific to gene expression data. Sean

Very useful for finding packages/functions on various topics are the task views pages for R and BioC: R: http://cran.at.r-project.org/web/views/ Task views on clustering http://cran.at.r-project.org/web/views/Cluster.html BioC: http://www.bioconductor.org/packages/release/Software.html On Wed, Apr 14, 2010 at 05:53:49AM -0400, Sean Davis wrote: > On Tue, Apr 13, 2010 at 11:27 PM, Rohit Farmer <rohit.farmer at="" gmail.com=""> wrote: > > Hello everyone ... > > > > I just wanted to know what are the different cluster methods available > > in bioconductor apart from K-means and hierarchical clustering and > > what are the libraries can be used for the same purpose ....

It requires a different pre-processing using 'mmgmos' from the same package to also extract uncertainty information from the arrays, but the resulting extra power can be really useful in some situations.
