Static maps

Description

Function to produce static maps from an object of class sf, IT, EU, US, or WR.

Usage

mapping(data = NULL, var = NULL, colID = NULL,
        type = c("static", "interactive"),
        typeStatic = c("tmap", "choro.cart", "typo","bar"),
        add_text = NULL, subset = NULL, facets = NULL, aggregation_fun = sum,
        aggregation_unit = NULL, options = mapping.options(), ...)

Arguments

data

an object of class sf, IT, EU, US, or WR

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

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 aggregate

options

a list with options using mapping.options function

...

further arguments

Details

It is a general function to map data. We can externally provide the coordinates with the variable to map, or the coordinates and the data to link.

If coordinates are provided and data is NULL, the function map the var in coordinates. If data is not NULL, then the function link data and coordinates, and the var is get from the data provided in input. If only data are provided without coordinates, the function search the colID among the the coordinates dataset provided by https://github.com/mappinguniverse/geospatial, to link the ids with coordinates. For search look at SearchNames

Value

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