plot.Lc: Plot Lorenz Curve

In ineq: Measuring Inequality, Concentration, and Poverty

Description

plotting method for objects of class "Lc" (Lorenz curves)

Usage

## S3 method for class 'Lc'
plot(x, general=FALSE, lwd=2, xlab="p", ylab="L(p)",
    main="Lorenz curve", las=1, ...) 

Arguments

x	an object of class "Lc"
general	logical. If TRUE the generalized Lorenz curve will be plotted
lwd, xlab, ylab, main, las, ...	high-level plot function parameters.

Examples

## Load and attach income (and metadata) set from Ilocos, Philippines
data(Ilocos)
attach(Ilocos)
## extract and rescale income for the provinces "Pangasinan" und "La Union"
income.p <- income[province=="Pangasinan"]/10000
income.u <- income[province=="La Union"]/10000
## compute the Lorenz curves
Lc.p <- Lc(income.p)
Lc.u <- Lc(income.u)
## plot both Lorenz curves
plot(Lc.p)
lines(Lc.u, col=2)
