• gfrance@plotOrder,

• gfrance@bbox,

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)
 
if (FALSE) {
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"),
