Area between curves

This is what I like about ‘R’. This one line is enough to apply a shade of color
to the area between two curves. Apart from the functional programming aspects(

polygon( c(data$Time, rev(data$Time)),
         c(as.numeric(data$Used), rev(as.numeric(data$Committed))),
         col = "antiquewhite1",
		 border = NA )
