Sorry, but this doesn't make sense. read.delim() reads tab-separated
files just as easily as read.csv() reads comma-separated ones (and in
both cases, there is a "2" variant for locales in which comma is used
as decimals separator as in 0,02 EUR).

As others have pointed out, the real issue was how to specify a
filename, and the use of the backslash escape. And Duncan M. pointed
towards file.choose() as a user-friendly helper on Windows.
