The format is:
Formal class 'SpatialPolygonsDataFrame' [package "sp"] with 5 slots: gfrance@data,

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")
spplot(gfrance, "Crime_prop")
# Note that spplot assumes all variables are on the same scale for comparative plots
# These plots do that, but it would be more appropriate to scale each separately, as in the above
