spMaps: Get custom Europe map ('SpatialPolygonsDataFrame')

In spMaps: Europe SpatialPolygonsDataFrame Builder

Get custom Europe map (SpatialPolygonsDataFrame)

Description

This function builds a custom Europe map and return a SpatialPolygonsDataFrame. The output can be use by example in mapLayout with the map argument.

Usage

getEuropeReferenceTable()

getEuropeCountries(mergeCountry = TRUE)

getEuropeStates()

getSpMaps(countries = "all", states = NULL, mergeCountry = TRUE)

Arguments

mergeCountry	boolean. Merge country ? (UK, Belgium ...). Default to TRUE.
countries	character. Vector of wanted countries, without details / states. Must referred to code column of the reference table getEuropeReferenceTable. "all" (default) keep all countries
states	character. Vector of wanted countries, with details / states. Must referred to code column of the reference table getEuropeReferenceTable. "all" keep all countries. NULL as default.

Value

SpatialPolygonsDataFrame

Examples

# default map : Europe without states
europe_cty <- getSpMaps()
plot(europe_cty)

# subset on some countries
ref_table <- getEuropeReferenceTable()

italy_spain_fra <- getSpMaps(countries = c("FRA", "ITA", "ESP"))
plot(italy_spain_fra)

## Not run: 
italy_spain_fra_states <- getSpMaps(countries = NULL, states = c("FRA", "ITA", "ESP"))
plot(italy_spain_fra_states)

# combine countries and states
combine_map <- getSpMaps(countries = c("ITA", "ESP"), states = "FRA")
plot(combine_map)

# build your custom map : you can use directly data
# to subset the area you really want
europe_states <- getEuropeStates()
europe_countries <- getEuropeCountries()

# for example, have a look to GBR states map
summary(europe_states)
gbr_states_districts <- europe_states[
   europe_states$code %in% "GBR" &
   europe_states$type %in% "Administrative County",]
plot(gbr_states_districts)

# combine with another map : you just have to have the same columns...
# getSpMaps only return "name" and "code" column
custom_states <- rbind(
    getSpMaps(countries = NULL, states = "FRA"),
    gbr_states_districts[, c("name", "code"), drop = FALSE])

plot(custom_states)
