In addition to that, there are some more parameters for the shade(
function, those for the left and right sides of the shaded area. For
example, shade(low,high,-1,4) will shade the area between "low" and
"high" between x=-1 and x=4. These DO NOT use functions for x, but they
allow you to decide where to start and stop the shading.
