Plot Lorenz Curve
plotting method for objects of class "Lc" (Lorenz curves)
## S3 method for class 'Lc'

## 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)
