excel files and R
And there is Thomas Baier's and my RCOM package which would allow to run R from within Excel or exchange data between Excel and R with R as the main interface.

If you really want to run windows from R (in my experience it is much better to reside entirely within R) then I think that you need to use Duncan Temple Lang's RDCOM package ( http://www.omegahat.org/ ). It works well and robustly for connections to other packages and I have tested it for Excel.
