Lists the orderings that can be passed to order in energypal(),
energypal_table() and the scale functions, together with the note and
source recorded for each.
Value
A data frame with one row per available ordering and columns
order, kind ("declared", "property" or "computed"), n, note,
source and url.
Presentation only
Orderings arrange legends and chart series. They are not model inputs. The sequences, and the numeric properties some of them derive from, are indicative values chosen so that charts read sensibly; they are not validated figures and must not be used in calculations. Every declared ordering carries a note saying so, printed by this function.
Examples
energypal_orders("carriers")
#> order kind n
#> 1 carbon_intensity declared 9
#> 2 dispatchability declared 10
#> 3 merit_order declared 8
#> 4 renewability declared 10
#> 5 spec computed 93
#> 6 alpha computed 93
#> 7 hue computed 93
#> 8 lightness computed 93
#> 9 chroma computed 93
#> note
#> 1 Presentation only. Orders chart series and legends; NOT a model input and not to be used in calculations. Lifecycle medians vary widely with fuel quality, plant vintage, capacity factor and system boundary.\n
#> 2 Presentation only. Conventional order for drawing a generation stack, dispatchable first and variable last. Not an operational ranking; real flexibility is plant- and system-specific.\n
#> 3 Presentation only. Indicative short-run marginal cost order for drawing dispatch stacks. Real merit order is system- and time-specific and must come from the model, never from this file.\n
#> 4 Presentation only. Groups by origin - fossil, then other non-renewable, then renewable - as most published energy-mix charts stack them.\n
#> 5 Computed from the palette itself. Presentation only.
#> 6 Computed from the palette itself. Presentation only.
#> 7 Computed from the palette itself. Presentation only.
#> 8 Computed from the palette itself. Presentation only.
#> 9 Computed from the palette itself. Presentation only.
