[BioC] Detecting overrepresented genomic loci

Hi all,

My goal is to discover regions with multiple adjacent genes coordinately 
regulated. Are there any packages that would allow one to test for genomic 
loci that are overrepresented in a subset of genes versus the remaining 
genes on the chip? I have tried using the geneplotter package to visualize 
the genomic distribution of differentially expressed genes, however, I 
have found it difficult to identify candidate loci from these plots 
because neighboring genes are indistinguishable from each other on the 
output graphic.
