Static maps for Europe

Function to produce static maps for European statistical unit.

Usage

mappingEU(data, var = NULL, colID = NULL,
          type = c("static", "interactive"),
          typeStatic = c("tmap", "choro.cart", "typo", "bar"),
          unit = c("nuts0", "nuts1", "nuts2", "nuts3", "urau"),
          year = c("2021","2016", "2013", "2010", "2006", "2003"),
          matchWith = c("nuts", "id", "iso2", "iso3", "country_code"),
          scale = c("20", "60"), dir = NULL, show_eu = TRUE,
          add_text = NULL, subset = NULL, facets = NULL,
          aggregation_fun = sum, aggregation_unit = NULL,
          options = mapping.options())

Arguments

data

a data.frame object with variables to display or a EU object produced by EU function

var

character value(s) or columns number(s) indicating the variable to plot

colID

character value or columns number indicating the column with unit names

type

if generates static or interactive map

typeStatic

type of static map

unit

the type of European statistical unit to check

year

year of the unit

matchWith

the type of id to check:

`"nuts"`	if nuts names).
`"id"`	if nuts id.
`"iso2"`	if iso2 code.
`"iso3"`	if iso3 code.
`"country_code"`	if Eurostat code

scale

the scale of a map

dir

local directory in which shape files are stored

show_eu

logical value set to TRUE indicating if the map entire map is drawn or only the coordinates linked to the input data

add_text

character name indicating the column with text labels

subset

a formula indicating the condition to subset the data. See the details

facets

variable(s) name to split the data

aggregation_fun

function to use when data are aggregated

aggregation_unit

variable name by which the unit are aggregated

options

a list with options using mapping.options function

Details

If data is a object of class "EU" generated using the EU function, the arguments unit, year, and matchWith are ignored, because the object already contains the coordinates.

The aggregation_unit provides an aggregation for a user specified variable in data, or for larger statistical unit, automatically provided when the function link the data with the coordinates. For example, if data are of type nut2, we will have variables for larger aggregate unit, that is nuts1 and nuts0 variables. Look at EU for more details.

subset provide an expression to subsetting the data using a formula, with the logical operators. For example data can be subsetting as follows: ~I("Variable 1" == "condition 1" & "Variable 2" != "condition 2") or for example, ~I("Variable 1" > "condition 1" | "Variable 2" != "condition 2").

Value

Returns a map. For tmap type, the function also returns a tmap object.
