[BioC] SAM with censored survival data on exprSet

[mpg33 at drexel.edu]

I want to use significance analysis of microarrays to identify significantly altered genes selected on the basis of censored survival data.  I know you can do this using the samr package, however this package does not accept data in the form of exprSets and phenoData as inputs.  The sam function in the siggenes package uses exprSets but does not have an option for censored survival data.  Is there a reason for this?  A quick fix to this problem?  

Thanks, 
Mike
