Particularly, Fig. 07 in the Graph gallery.
Package spmaps can be used to extract desired boundaries from the mapdata
and convert them to the format suitable for sp and others.

Hi Lawrence,
You could use the gstat (geostatistics) package to perform an
interpolation, it also requires the package sp. It offers inverse
distance interpolation and several forms of kriging. Making an
interpolation would look something like:
library(gstat) # Also loads sp
Hi-
I am trying to find a way to diffuse GIS data on a European map. I have a
dataset consisting of particular locations scattered across Europe,
along with magnitude and value information. I can plot these as discrete
points with something like the following:
