If you have a dataset with several (or all!) countries/ regions/ ages/ etc and you want a short call function to plot without having to modify the ggplot2 code every time (e.g. a certain country for a certain year), here’s a solution.

The next step will be to use facet_wrap to select sub-national administrative units at once to be compared against the national plots.
Data can be found for Iraq at national level on my github page.
