Usage

plot_curve_area(x, y, y.base = 0, col = NA, ...)

Arguments

x	vector of x coordinates
y	vector of y coordinates
y.base	y coordinate of horizontal line that closes the area
col	colour of area to be plotted. Default: NA
...	further arguments given to polygon such as border (colour of the border of the polygon)

Examples

  x <- seq(-pi, pi, pi/8)
  y <- sin(x)
