Very nice article. I am trying to reproduce it and having problems:

1 - This library/instll will not load (Are you sure it is not library(geoData)

# Get the data
library(geodata)

2 - Wher is this “mapslib” data stored? I see nothing referenced on your github pages

 # Cache map data
mydir <- "~/R/mapslib/misc" "

THanks. Jim
