locational_gini_curve {EconGeo} | R Documentation |
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, pdf_location = NULL)
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? Defaults to FALSE. If set to TRUE, a pdf with all will be compiled and saved to R's temp dir if no 'pdf_location' is specified. |
pdf_location |
Output location of pdf file |
Value
No return value, produces a plot or pdf.

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 = TRUE
)
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, pdf = FALSE)
locational_gini_curve(mat, pdf = FALSE)
## Save output as pdf
locational_gini_curve(mat, pdf = TRUE)
## To specify an output directory for the pdf,
## specify 'pdf_location', for instance as '/Users/jones/locational_gini_curve.pdf'
## locational_gini_curve(mat, pdf = TRUE, pdf_location = '/Users/jones/locational_gini_curve.pdf')
