curveLorenz: Lorenz Curve

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).
