Re: [R] Trouble with Spatial Data Example Script

Lorenzo Isella Sat, 11 Aug 2012 10:03:29 -0700

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 thesource("myfile.R") command, then I fall back to the case that started thisthread 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 matterwhether 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

 [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
