It has about 29000 rows and 20 columns (incl col.name).
How would you set this up in edgeR if you want to compare the 10 first with
the 10 last?
Please ask questions about Bioconductor packages on the Bioconductor
mailing list
http://bioconductor.org/help/mailing-list/
There have been recent time-course questions on the mailing list, so
it's good to browse recents posts. Remember to include sessionInfo().
Have you looked at the extensive vignette for this package
http://bioconductor.org/packages/2.10/bioc/html/edgeR.html
and limma, and taken a stab at answering your own question? It helps to
see where you're coming from...; for this particular question and if
you're statistically naive it might help to have a conversation with
someone local who is a little versed in statistics.
