If you specified the entire column there may have been something it didnt like

use just the range of data

=sumif(source range,"R",rate range)

If it still doesn't work, check that the Rs are realy just "R" with
something like
=if(cell="R","yep", "Nope")
on a couple of the cells with R in them
you may have to use the clean function if there are addtitional things in
the cells
