All, I am searching for a bioconductor package that implements rank-invariant normalization. More importantly, I would like to obtain a list of genes that appear to be rank invariant. I don't want the actual normalization. I see that the HTqPCR package has an implementation. Has anyone used any other implementations? Thanks for your help. Regards, Juliet

That will give you a boolean index of the invariant input values. d <- rnorm(1000) ref <- rnorm(1000) norm <- normalize.invariantset(data=d, ref=ref) norm[["i.set"]] HTH \Heidi > I see that the HTqPCR package has an implementation. > > Has anyone used any other implementations? > > Thanks for your help. > > Regards, > > Juliet > > _______________________________________________ > Bioconductor mailing list > Bioconductor at r-project.org > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: > http://news.gmane.org/gmane.science.biology.informatics.conductor >
