ARPALdf_Summary_map {ARPALData}R Documentation

Generate a map of summary statistics for a given ARPALdf data.frame

Description

'ARPALdf_Summary_map' represents on a map (polygon of Lombardy) the data contained in a data frame of class 'ARPALdf' containing the values or the descriptive statistics by station. Data can be either a ARPALdf of observed data (from 'get_ARPA_Lombardia_xxx' commands) and an ARPALdf obtained as summary descriptive statistic (from 'ARPALdf_Summary' command).

Usage

ARPALdf_Summary_map(
  Data,
  Title_main,
  Title_legend = "Variable",
  Variable,
  prov_line_type = 1,
  prov_line_size = 1,
  col_scale = c("#00FF00", "#FFFF00", "#FF0000"),
  val_midpoint = NULL,
  xlab = "Longitude",
  ylab = "Latitude"
)

Arguments

Data

Dataset of class 'ARPALdf' containing the values or the descriptive statistics to plot on the map. Data can be either a ARPALdf of observed data (from 'get_ARPA_Lombardia_xxx' commands) and an ARPALdf obtained as summary descriptive statistic (from 'ARPALdf_Summary' command).

Title_main

Title of the plot.

Title_legend

Title fo the legend

Variable

Summary variable to represent

prov_line_type

Linetype for Lombardy provinces. Default is 1.

prov_line_size

Size of the line for Lombardy provinces. Default is 1.

col_scale

Vector indicating the minimum, the middle and the average point colors. Default is c("green","yellow","red").

val_midpoint

Numeric. Value associated to the middle-point scale color. Default is NULL (midpoint is set equal to the average of the variable to represent).

xlab

x-axis label. Default is 'Longitude'.

ylab

y-axis label. Default is 'Latitude'.

Value

A map of selected stations across the Lombardy region

Examples


## Download daily air quality data from all the stations for year 2020
d <- get_ARPA_Lombardia_AQ_data(ID_station = NULL, Year = 2020, Frequency = "daily")
## Summarising observed data
s <- ARPALdf_Summary(Data = d)
## Mapping of the average NO2 in 2020 at several stations
ARPALdf_Summary_map(Data = s$Descr_by_IDStat$Mean_by_stat,
        Title_main = "Mean NO2 by station in 2020", Variable = "NO2")
