Seasonal adjustment is easy but getting hold of data can be hard. In this case I wrangle Samoa's monthly visitor arrivals data from 2017 to present and then use the seas and fable R packages to seasonally adjust it and ask if there is an impact from Iran war fuel crisis (there isn't evidence of one yet).
