Maps in R: Introduction - Drawing the map of Europe

R blog By December 19, 2012 Tags: , , 18 Comments

This post is a brief follow-up to a question that appeared some time ago on the “The R Project for Statistical Computing” LinkedIn group, which I’m reporting here:

How can I draw a map of MODERN Europe?

Hi, I'm trying to draw a map of modern Europe but I've found only maps of twenty years ago, with Yugoslavia and Czechoslovakia still united!!!
Does anyone know where I can get a more recent map to be employed with packages such as 'sp' or 'maps'?
Thank you very much!

Two different solutions to the above question will be provided here, using two different R packages.
