Caption line naming the unit-cost rates behind the cost plots

Formats the unit-cost rates (EUR per m2 / m3, see default_cost_rates()) as a single-line caption for the cost plots, so every figure names the rates its EUR values were computed with. Used as the default caption of plot_cost_vs_overflow_volume(), plot_cost_vs_evaporation() and plot_cost_overflow_boxplot() (rendered by ggplot at the bottom of the PDFs) and passed to plotly_add_caption() for the interactive HTMLs (plotly::ggplotly() drops ggplot captions).

Usage

cost_rates_caption(lang = c("de", "en"), cost_rates = default_cost_rates())

Arguments

lang

Character. "de" or "en".

cost_rates

list of unit costs as returned by default_cost_rates().

Value

character(1), a single line.

Details

If the costs were computed with non-default rates, pass the same cost_rates list here so the caption matches the numbers.

Examples

cost_rates_caption("de")
