[BioC] bioconductor implementations to find rank invariant genes

[Juliet Hannah]

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
