Map of France in 1830 with the Guerry data
Description
gfrance
is a SpatialPolygonsDataFrame
object created with the
sp

France as it was in 1830, together with the Guerry
data frame.
Usage
data(gfrance)
Format
The format is: Formal class 'SpatialPolygonsDataFrame' [package "sp"] with 5 slots:
-
gfrance@data
, -
gfrance@polygons
, -
gfrance@plotOrder
, -
gfrance@bbox
, -
gfrance@proj4string
.
See: SpatialPolygonsDataFrame
for descriptions of some components.
The analysis variables, represented in gfrance@data
are described in Guerry
.

Examples
library(sp)
data(gfrance)
names(gfrance) ## list @data variables
plot(gfrance) ## just show the map outline
# Show basic choropleth plots of some of the variables
spplot(gfrance, "Crime_pers")
# use something like Guerry's pallete, where dark = Worse
my.palette <- rev(RColorBrewer::brewer.pal(n = 9, name = "PuBu"))
spplot(gfrance, "Crime_pers", col.regions = my.palette, cuts = 8)
spplot(gfrance, "Crime_prop")
# Note that spplot assumes all variables are on the same scale for comparative plots
# transform variables to ranks (as Guerry did)
## Not run:
local({
gfrance$Crime_pers <- rank(gfrance$Crime_pers)
gfrance$Crime_prop <- rank(gfrance$Crime_prop)
gfrance$Literacy <- rank(gfrance$Literacy)
gfrance$Donations <- rank(gfrance$Donations)
gfrance$Infants <- rank(gfrance$Infants)
gfrance$Suicides <- rank(gfrance$Suicides)
spplot(gfrance, c("Crime_pers", "Crime_prop", "Literacy", "Donations", "Infants", "Suicides"),
layout=c(3,2), as.table=TRUE, main="Guerry's main moral variables")
})
