[BioC] distribution of genes differentially expressed

[Phguardiol at aol.com]

Hi all,
I d like to know if there is a package in BioC that can identify genes that 
are differentially expressed between 2 conditions and  analyze their 
distribution along the chromosomes to say if their distribution is random or 
if it has a non random distribution with some sort of clusters in some part 
of the chromosomes... for instance, a tool that could help to detect 
translocations, loss or gain of chromosomes from the microarray data...
thanks
Philippe
