It isn't mentioned because it isn't needed.

I'd try

read.csv(filename,sep="\t") # for tab-separated files

Shouldn't happen quite like that.

I have a file on my XP box, in my "My Documents" folder, called 
"foo.txt".  It's a two-column text file, tab-separated.  First column is 
  the numbers 1 to 12.  Second column is some random numbers.

Notice the "/" rather than the "\" as the directory delimiter.

Cheers
