ggplot2 - How do I get swedish characters in R -


i trying map in ggplot2 in r. use function rgdal package:

mapa <- readogr(dsn=path.expand("c:/~/swe_adm_shp"),layer="swe_adm2")

than do:

fortify(mapa)  ggplot(mapa, aes(x = long, y = lat, group = group)) +   geom_polygon(fill = "blue", col = "white") +   coord_map()

it works fine when @ 

head(mapa)
