[R] Plotting data on a map

[phiroc]

Hello,

I would like to generate a small map (say 10cm x 10cm) of France showing 
cumulative numbers by Distribution Center
stored in a database:

DISTRIBUTION_CENTER COUNT
Paris   122
Paris   3
Paris   21
Lyon12
Lyon
Lyon33
Grenoble55
Grenoble999
Grenoble99
...

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.

Philippe

Subject: Re: Plotting Data on a

Map



Hadley,





Thank

you!



I doing this, I've
encountered an encountered and unexpected difference between the   
graphs on my
Mac and my Windows machines. It appears that there is a default  
setting

different between the two
programs.



Using the same commands
on both Mac and Windows, I found that the polygon borders are  
plotted on the
Mac, but not on Windows, so on the Mac I see the country borders,  
but on Windows
I do not. On the Mac, it looks like the default for geom_polygon is  
something
like size = 0.01, colour = gray50. On Windows, it's more like  
colour =
alpha(gray50, 0), though in fact the visibility of polygon  
borders seems to be

independent of both the size and colour
settings.



Regards,


Tom
