Your columns all end up as FACTOR variables (i.e. Canada is 126 by coincidence). Try:
str(colDeathTot)
To overcome this I changed
colDeathTot$TotalDeaths <- colDeathTot$NULL.NUMERIC.VALUE
to
colDeathTot$TotalDeaths <- as.numeric(as.character(colDeathTot$NULL.NUMERIC.VALUE))
and it seems to work. As these are absolut numbers for road death China comes up with 275983 casualties in 2010, followed by India. Putting the numbers in relation to population size would be a good idea to enhance the statement.
