The cartography package is a great alternative to make maps with R. This post explains how to build a bubble map using it, with explanation and reproducible code.
cartography package is a very good alternative to
the other tools presented in the
gallery for building maps.
It notably allows to:
# Library library(cartography) library(sp) # Upload data attached with the package. data(nuts2006) # Now we have a geospatial object called nuts2.spdf containing the shape of european regions. We can plot it with the plot function. # summary(nuts2.spdf) # We also have a dataframe with information concerning every region. # head(nuts2.df) # Both object have a first column "id" that makes the link between them. # Plot Europe plot(nuts0.spdf, border = NA, col = NA, bg = "#A6CAE0") plot(world.spdf, col = "#E3DEBF", border = NA, add = TRUE) plot(nuts0.spdf, col = "#D1914D", border = "grey80", add = TRUE) # Add circles proportional to the total population propSymbolsLayer(spdf = nuts0.spdf, df = nuts0.df, var = "pop2008", symbols = "circle", col = "#920000", legend.pos = "right", legend.title.txt = "Total\npopulation (2008)", legend.style = "c") # Add titles, legend... layoutLayer(title = "Countries Population in Europe", author = "cartography", sources = "Eurostat, 2008", scale = NULL, south = TRUE)
