Sometimes there is an invisible something in a row of data in Excel ... a
blank space, a formatting something, i don't know ... that causes this to
happen. Open the file in Excel, select the entire row (by clicking on the
row number), right click for a menu, select "Delete", then save the
file
and try your R script again. It might work.
