I have a problem for building barplot.
I am working on air traffic in different countries. I would like to get barplots for each countries with the different airport names in the X axis. The Y axis will show the quantity of airlines using the airport.
My plan is to make the script for 1 country and to replicate it manually for the others.
in my data, I have in the different columns: Country / aiport / destination. So each rows is actually one airline that is using the airport.
Do you have an idea about how to do this?
For now I have this idea:
UK<-traffic[traffic$Country=="UK",]
UK$airport <- as.factor(UK$airport)
countUK<-table(UK$airport)
barplot(countUK)
This is not working, I have a bunch of airports that are not in UK in the X axis...
Thanks for your help
