Map projectin for Europe...

Hi, I has a meteorology project in which I have to map average wind speeds over EU, as well as European countries' boundary. I have been looking online for free European maps like the one I can find on US Census for N. America. But it seems like google doesn't hit anything useful. I wonder if some Rusers from Europe might know where I could find free EU map with each country's boundary.
Here is a link to the world map with country boundaries which was discussed on the list in September last year, updated for R >= 2.4. http://spatial.nhh.no/R/etc/world_countries_24.rda load("world_countries_24.rda") You'll need to subset the object to choose the countries of Europe that you require, then use the spTransform() method in rgdal to go to the standard EU Lambert AEA: CRS("+init=epsg:3035") Hope this helps, Roger
Just a few quick questions: About the best or appropriate projection for Europe, I am thinking to use lambert conformal conic or lambert azimuthal equal area. Are these good for Europe? My colleague uses the latter lambert for N. America mapping. About plotting a map boundary, if I do not rely on mapproj and shapefile library, simply using plot() or xyplot() gave me a disatrerous map, where points are not sequentially connected at all.. I believe I would have to add some kinds of flags to the boundary dataset. Could anyone kindly give me advice on these problems although I have never changed map projections in R, but I will look into mapproj library as a start? Thanks in advance. taka
