David,

Feel free to reply to the list; everyone learns by doing so.

I'm just guessing, but it looks like the file that you sent is an
excel spreadsheet.  It was impossible to tell, though.  You will need
to save that as a text file (csv) from excel before you can read it
into R using read.csv().  Your file should be entirely readable in
textedit if you want to read it with read.csv().  If I am incorrect
about the file type, then you'll need to send along a text version.
