A named character vector in the shape every `*_all()` function expects: the **name** is the indicator key reiod knows, the **value** is the column in [eiod_demo] that holds it.
Details
It is shipped rather than retyped in each example, and it exists at all because [eiod_demo]'s columns are deliberately *not* named after the indicator keys. Write the equivalent line for your own data once, near the top of your script, and every later call reads from it.
Examples
data(eiod_demo_map)
eiod_demo_map
#> landtotal landarable landpasture ghg
#> "land_total_m2yr" "land_arable_m2yr" "land_pasture_m2yr" "ghg_kgco2e"
#> eutroph water biodiv
#> "eutroph_gpo4e" "water_litres" "biodiv_pdf"
# the same shape, for your own data:
# my_map <- c(ghg = "ghg_total_kg", biodiv = "pdf_year", water = "water_l")
