Plot a locational Gini curve from regions - industries matrices

Description

This function plots a locational Gini curve following Krugman from regions - industries matrices.

Usage

locational.Gini.curve(mat, pdf = FALSE)

Arguments

mat	An incidence matrix with regions in rows and industries in columns. The input can also be a vector of industrial regional count (a matrix with n regions in rows and a single column).
pdf	Logical; shall a pdf be saved to your current working directory? Defaults to FALSE. If set to TRUE, a pdf with all locational Gini curves will be compiled and saved to your current working directory.
pop	A vector of population regional count

Examples

## generate a region - industry matrix
mat = matrix (
c (100, 0, 0, 0, 0,
0, 15, 5, 70, 10,
0, 20, 10, 20, 50,
0, 25, 30, 5, 40,
0, 40, 55, 5, 0), ncol = 5, byrow = T)
rownames(mat) <- c ("R1", "R2", "R3", "R4", "R5")
colnames(mat) <- c ("I1", "I2", "I3", "I4", "I5")

## run the function (shows industry #5)
locational.Gini.curve (mat)
locational.Gini.curve (mat, pdf = TRUE)
