[R] Plot map by region using kasc and adehabitat

[Alex Olssen]

Hi there,

I thought it would be useful to answer my own question for anybody
else searching Google.

An easy way to split a national map into smaller maps at lower levels
of aggregation is to use the function
mask()
in the package
raster
