Trouble with Spatial Data Example Script

Can you get other plotting commands to work? E.g.

plot(1:5, 1:5)

Thanks for your reply.
I am running R 2.15.1 on debian testing, amd64 architecture.




~$ R

R version 2.15.1 (2012-06-22) -- "Roasted Marshmallows"
Copyright (C) 2012 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
Platform: x86_64-pc-linux-gnu (64-bit)


and when I run the script, this is what I see



source('map-switzerland.R')
[1] "gadm"

gadm contains the data, but I do not see any map.
Any hint about what is going on?
Cheers

Lorenzo

What version of R are you using? What operating system does your
computer use? When the command, print(load(con)), runs, what message

do

you see?

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
