And I can only underscore Ben's point: if you are writing a package, please try to use some of the standard tools to read/write files, compute simple summary statistics and use standard data structures. While it may take a little longer initially your code will work better with Bioconductor and you will get most new features more easily than writing them yourself. And of course these other packages have often been widely tested, relieving you of such a need. As always, folks here in Seattle are available to help with such integration. best wishes Robert Ben Bolstad wrote: > Although this doesn't really directly answer your question .... > > You might consider prompting the authors of the sscore package to > consider building on top of the standard structures and parsers.
