Trouble with Spatial Data Example Script

Hello,
The situation is a bit odd.
If I open an R session and I paste there the script, then it does work.
However, if I save it as a text file and then I run it with the
source("myfile.R") command, then I fall back to the case that started this
thread i.e. I see nothing.
Does anybody have a clue at what is going on?
I paste below the output of sessionInfo(), which is the same no matter
whether I paste the commands in a shell or use a .R file.


sessionInfo()
R version 2.15.1 (2012-06-22)
Platform: x86_64-pc-linux-gnu (64-bit)

locale:
 [1] LC_CTYPE=en_US.UTF-8       LC_NUMERIC=C
 [3] LC_TIME=en_US.UTF-8        LC_COLLATE=en_US.UTF-8
 [5] LC_MONETARY=en_US.UTF-8    LC_MESSAGES=en_US.UTF-8
 [7] LC_PAPER=C                 LC_NAME=C
 [9] LC_ADDRESS=C               LC_TELEPHONE=C
[11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base

other attached packages:
[1] sp_0.9-99

loaded via a namespace (and not attached):
[1] grid_2.15.1    lattice_0.20-6


Many thanks

Lorenzo

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

The script is working for me. Did you get any error or warning

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
