Dear D,
as a general remark that may also be relevant to some others here, I
think you would have a better chance of getting replies to your posts if
you revealed your real name. I for one rarely feel inclined to answer to
anonymous posts.
You may also want to read the posting guide, there are a number of
helpful suggestions that may help you to have more meaningful
interactions: http://www.bioconductor.org/docs/postingGuide.html
Best wishes
Wolfgang
