depending on the type of arrays you have, the Bioconductor packages
Ringo and oligo may be of interest to you. Please have a look at their
I guess you mean that in your ChIP an antibody against a histone tail
modification has been used. We have created and used the package Ringo,
which relies on limma, for such an analysis, but there are also a number
of other valuable approaches available through Bioconductor, for example
Hope this helps to get you started,
