EU {mapping} | R Documentation |
Object of class EU
Description
Creates an object with data and coordinates of class EU
for European countries to use with mapping
functions or available in other R "maps" packages.
Usage
EU(data, colID = NULL,
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"), show_eu = TRUE,
subset = NULL, add = NULL, new_var_names = NULL,
aggregation_fun = sum, aggregation_unit = NULL, aggregation_var = NULL,
facets = NULL, check.unit.names = TRUE, dir = NULL,
use_cache = TRUE, print = FALSE, use_internet = TRUE, crs = NULL)
Arguments
data |
a data.frame object with variables to display | ||||||||||
colID |
character value or columns number indicating the column with unit names | ||||||||||
unit |
the type of European statistical unit | ||||||||||
year |
year of the analysis | ||||||||||
matchWith |
the type of id to check:
| ||||||||||
scale |
the scale of the map | ||||||||||
show_eu |
logical value set to TRUE indicating if the entire map is drawn or only the coordinates linked to the input data | ||||||||||
subset |
a formula indicating the condition to subset the data, see the Details | ||||||||||
add |
a formula to add new transformed variables starting from the variables in the | ||||||||||
new_var_names |
a character value or vector indicating the names of the new variables created in | ||||||||||
aggregation_fun |
function to use when data are aggregated | ||||||||||
aggregation_unit |
variable name by which the unit are aggregated | ||||||||||
aggregation_var |
variable name with value to aggregate | ||||||||||
facets |
variable(s) name to split the data | ||||||||||
check.unit.names |
a logical value indicating if the | ||||||||||
dir |
local directory in which shape files are stored | ||||||||||
use_cache |
a logical value indicating whether use the cache | ||||||||||
print |
a logical value indicating whether print the nomatched names | ||||||||||
use_internet |
a logical value indicating wheter the coordinates are downloaded from https://github.com/mappinguniverse/geospatial. If | ||||||||||
crs |
coordinate reference system. Look at |
Details
The function links (automatically) the id in the data
and the coordinates for the given unit
.
Since the names (or codes) provided in the data
given in input must be checked with the unit
names (or codes) available in the package (as provided by Eurostat), the check.unit.names
provides a preliminary check.
subset
provide an expression to subset the data
, using a formula with the logical operators. For example, sub-samples of the data can be selected as follows: ~I("Variable 1" == "condition 1" & "Variable 2" != "condition 2")
or for example, ~I("Variable 1" > "condition 1" | "Variable 2" != "condition 2")
.
Value
An object of class EU
, with data and coordinates to use in functions which perform map.
