ARPALdf_Summary_map | R Documentation |
'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).

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'. |
