Subject: [R] Trouble with Spatial Data Example Script
Dear All,
I need to do something relatively simple: generate a map of Europe and
paint the various states with different colors (only 3-4 are needed)
according to a rule.
I would like to keep it as simple as possible and the script resorting
to
the sp package that I found at
http://bit.ly/Oc71ub
is exactly what I am looking for (I need to repeat the exercise with
Europe instead of Switzerland and to have a legend).
However, when I try to run the script (which I also paste at the end of
the email), well, nothing happens and I certainly do not see a map of
Switzerland.
I am not familiar with the sp package, but am I missing the obvious?
Any help is appreciated.
Best Regards
Lorenzo
