Is the file an Excel file (probably from the extension) or can you open 
the file in notepad and read the text? If not, you need to save the file 
as csv or txt from within Excel and import the file into R as you tried 
above. You may also want to read the "R Data Import/Export" manual which 
is available from the r-project.org website.
