R help - Mar 2011 - How to draw a map of Europe?

Hi R users,

I need to draw a map of select European countries with country names shown
on the map.  Does anyone know how to do this in R?

Also, is it possible to draw a historical map of European countries using R?

Thanks a lot for your help.

This came up on this list a while ago and I was just using that example
for some work I'm doing but I have only copied what was posted
and added minor things to it. I can't give you actual answer
but you are probably just a few key words away from a google searhc.
?The term you are probably looking for
is "shapefile." Try that on google. For example,

http://www.google.com/#sclient=psy&hl=en&q=shapefile+cran+europe

turns up things that may help.

Adding a tiny bit to the material produced from a search and finding  
something from Roger Bivand in response to Rense Nieuwenhuis:

http://finzi.psych.upenn.edu/R/Rhelp02/archive/85586.html

require(maps)

  country2001 <- c("Austria", "Belgium",
"Switzerland",
  "Czechoslovakia", "Germany", "Denmark",
"Spain", "Finland", "France",
  "UK", "Greece", "Hungary", "Ireland",
"Israel", "Italy",
  "Luxembourg", "Netherlands", "Norway",
"Poland", "Portugal",
  "Sweden", "Slovenia")
  color2001 <- c("green",
"yellow","red","red", "red",
"red", "red",
  "red", "green", "red", "red",
"red", "red", "red", "red",
"red",
  "red", "blue", "red", "red",
"red", "orange")

europe$names[grep("Sicily", europe$names)] <-
"Italy:Sicily"
europe$names[grep("Sardinia", europe$names)] <-
"Italy:Sardinia"
match <- match.map(europe,country2001)
color <- color2001[match]
map(database="world", fill=TRUE, col=color,  
xlim=c(-25,70),ylim=c(35,71))

text(0, 45, "France")

If you want a map of France ~ 1830, see
