GADM Data Download
Dear All,
Please consider the snippet at the end of the email.
I often download some maps (in the R format) from
http://www.gadm.org/
However, when I run (typically more than once) a variation of the script
below (based on http://bit.ly/1b3W0Aa ),
I often get
Error in load(url(paste("http://gadm.org/data/rda/", fileName, "_adm", :

plot single part of the country using gadm map
Dear all,
in GADM map there are three levels (nation, province and precinct) for each
country of the world but for all of them you are never able to plot only one
part of a chosen country.
To be sure, I am trying to plot only one region of “Italy” and colour the
different precincts in it. So far I am able to colour...

Labelling a fortified GADM map plotted with ggplot and geom_map
I am having trouble getting data labels to display over the provinces in a GADM map of Canada.
Specifically, I need the variable "Number" from the data set "by_province", grouped by "region", to appear on the corresponding regions of the map.

Adding labels on maps (using sp, maptools, or something else suggested)
...ould like to place region names (or abbreviations if space is too
limited) on a map. I have tried the following, copying and adapting

3D Histograms on a Geographical Map
Dear All,
I like very much figure 2.a) and 2.b) of this paper
http://www.nature.com/srep/2013/130410/srep01640/pdf/srep01640.pdf
and I probably need a similar visualization.
Is anything like that doable in R? I have some experience with R and
gadm (gadm.org), but that is only to produce maps colored according to
a scalar.
I do not know how to visualize maps with a "perspective", let alone
adding the histograms in 3D.
Sorry for not providing an example script, but if I had one I would
not be posting at all.

Plotting data on a map
...999
Grenoble 99
...
I have looked at different graphing packages such as 'sp', 'raster' and 'ggplot2', but am not sure which one is most
appropriate for my purposes. Furthermore, I don't understand how you retrieve city coordinates from shp, gadm, etc., maps
generated, or downloaded from the web and then processed, with those packages (SHP, GADM, etc.), and plot data at those coordinates.
Any help would be much appreciated.
Many thanks.

Consulta mapas
...co la información es muy clara ni abarcativa.
¿Alguno/a trabaja con mapas en R y me puede indicar por donde encarar?
En principio mi interés es realizar mapas sencillos con información por
provincias y departamentos de Argentina.
(En cuanto a los shapefiles de Argentina tomé uno de aquí
http://www.gadm.org/ que no incluye las Islas Malvinas y el correcto del
Instituto Geográfico Nacional pero que al incluir el territorio antártico
lo hace menos practico).
Se agradece cualquier apunte o pista de por donde empezar a paso seguro.
Saludos y buen año!

x11() graphic device, displaying raster
Hello,
I am wondering about the X11() graphic device on Windows.
I try to plot a raster image but nothing gets displayed. I
found some pages where it is mentioned that x11() not
always supports raster rendering.
Is there any add on for x11, any update or any R-package
which solves that displaying problem in Windows?
What I try to test it is an example from the
package {raster}:
