[Bioc-devel] RFC: read.AnnotatedDataFrame

I would prefer not to drop the widget option, even if all we do is to 
say there is not one - please let us know that you want one. We should 
avoid changing signatures unless it is really necessary - and this seems 
to be aesthetic not semantic.

If you really want to help the Excel folks out, then you would use 
COM/DCOM to pull it directly from Excel, rather than force them to save 
as a file etc. I think it is quite straightforward and there have been 
several examples on the mailing list recently.

best wishes
