Hi That is quite usual. Excel is so widespread that almost everybody assumes it shall not contain mistakes and behaves correctly. The contrary is true. Spreadsheet often guess what user have on mind and "corrects" values to fit such assumption, let aside mistakes in coded functions.
R expects it is used by clever and able people and performs just what you tell it to do, not more not less. So whenever result does not fit your expectations, first proof your expectations.
