[R-sig-Geo] unable to customize a plot produced from a shapefile

[Alexandre Villers]

Hi,

You should have a look at the documentation (e.g. manuals) available on 
graphics in R (on the CRAN website, hhttp://cran.r-project.org/) to 
learn how to set the parameters of a R graphic, and more specifically at 
the spplot function (from package sp) for spatial objects (the ASDAR 
book of Roger Bivand et al. is worth the look  
http://www.springer.com/public+health/book/978-0-387-78170-9 ).
There are also several web sites showing this: just google "plot spatial 
data r" and you should find what you are looking for.
