[BioC] Finding genes with similar trend

[Christian De Santis]

Dear List,

I have data from a nutritional microarray experiment with 5 treatments where one component of the diet is varying in different proportions.
I have visually identified some genes that in my opinion share a common and possibly interesting trend. However, I was wondering if it exists a way to model this trend and extract other genes from the list that fit this trend. It is not necessarily a linear increase or decrease of expression (I know how to do that in Limma).

Perhaps anyone is aware of any functions of existing packages that can perform such a task? Thanks very much for your help, as usual!

Best Regards,
