[R] Drawing World map divided into 6 economic regions

[Christofer Bogaso]

Hi again,

I am trying to draw a World map which is divided into 6 Economic
regions as available in below link

http://www.worldbank.org/en/about/annual-report/regions

I am aware of various R ways to draw World map based on Countries like
one available in

http://stackoverflow.com/questions/24136868/plot-map-with-values-for-countries-as-color-in-r

However I do not want to put any individual Country boundaries,
instead the individual boundaries of 6 Economic regions in the World.

Can you please suggest how can I achieve such a World map. Any pointer
will be highly appreciated.

Thanks for your time.
