Load country boundaries into a SpatialPolygonsDataFrame object

1	load_boundary(x = NULL, country_code = "world", adm_level = 0, ...)

`x`	If missing, `link[raster]{getData}` function is used to load boundaries from the GADM project (http://gadm.org). Otherwise the name of the data source (see `readOGR`).
`country_code`	Country specified by three letter ISO code. Use function `ccodes` to get appropriate codes. If multiple countries are desired, provide a character vector of appropriate ISO codes.
`adm_level`	Level of administrative subdivision 0 = country, 1 = first level subdivision
`...`	Other arguments to `readOGR`.

A SpatialPolygonsDataFrame object storing country boundaries.

# Load boundary of Germany
ger_bnd <- load_boundary(country_code = "DEU", adm_level = 0);
plot(ger_bnd);

# Load boundary of several countries
bnd <- load_boundary(country_code = c("DEU", "ITA", "FRA"));
