curveLorenz: Lorenz Curve

In IC2: Inequality and Concentration Indices and Curves

Description

Plots an ordinary or generalized Lorenz curve.

Usage

curveLorenz(x, w = NULL, gener = FALSE, xlab = NA, ylab = NA, add = FALSE, grid = 0, ...)

Arguments

x	Numeric vector with non-negative values.
w	Numeric vector of sampling weigths (optional).
gener	If gener is TRUE, the generalized curve is plotted. Else, the ordinary curve is plotted.
xlab	Title for the x-axis.
ylab	Title for the y-axis.
add	If add is TRUE, only the curve is drawn. The device must contain a high-level plot.
grid	If grid >0, a grid is drawn, with spacing equal to 1/grid.
...	Further arguments to be used for drawing the Lorenz curve (see lines).
