I have been using the open air package for my research work. I have an air quality monitor located in my city and I am able to the plot the polar plots on the map for the respective pm levels. I was wondering if I could add the location of the sources also on the same map, I have a separate excel sheet for that, with the latitude and longitude. I have attached a sample code of my plot here. I am new to R and also new to this package, so please kindly consider this question.
library("openair")
library(openairmaps)
library("latex2exp")
library("dplyr")
wind_data = read.csv("Wind_TPH_Range.csv")
pm_range = c(wind_data$pm0.1,wind_data$pm0.3,wind_data$pm0.5,
wind_data$pm1.0,wind_data$pm2.5,wind_data$pm5.0,
wind_data$pm10.0)
pm_range = na.omit(pm_range)
lim = c(min(pm_range),max(pm_range))
mydata_sample = mydata[c(1:nrow(wind_data)),]
mydata_sample$pm0.1 = wind_data$pm0.1
mydata_sample$ws = wind_data$MeanWindSpeed
mydata_sample$wd = wind_data$MeanWindDirection
mydata_sample$lat = c(32.715)
mydata_sample$lon = c(-96.748)
mydata_sample = subset(mydata_sample, select = -c(so2,no2,o3,nox,pm10,co,pm25))
rev_default_col = c("#9E0142","#FA8C4E","#FFFFBF","#88D1A4","#5E4FA2")
title = "2023-01-01 - 2023-01-07"
polarMap(mydata_sample,pollutant = "pm0.1",main = title,k =30,cols = rev_default_col,key.position = "bottom",
key.header = TeX('$\PM_0._1\ Range(Minutes)$'), key.footer =NULL,
limits = c(lim[1],lim[2]),par.settings=list(fontsize=list(text=10)))
I have attached the plot below
I am expecting a plot that looks some what like this. (Btw, The polarmap plots background has to be transparent). Thanks in advance for the help :)
