Try this link http://thuban.intevation.org/download.html and search for the
freegis_worlddata either simplified or the detailed map. You may find Slovenia
on both of them. Import the shapefiles with the command read.shape from the
maptools library. The data you want to display in colour are stored in
imported.shp$att.data. So add the column with your data to this data.frame and
plot it with plot as explained in help pages of plot.Map. 

library(maptools)
w.data <- read.shape("countries.shp")
# edit data in w.data$att.data
plot(w.data, auxvar=w.data$att.data$your.variable) 
# play with aditional arguments of plot.Map as "recs" to plot only the european
part, either "fg" or "color" for the color ramp, "type" etc. 

All best, Lep pozdrav,
