Prepare data for a trajectory plot

Usage

prep_trajectory(
  data,
  convert_label = identity,
  span_5yr = FALSE,
  value_col = "percentage_of_initial_production_by_scope"
)

Arguments

data

A data frame. Requirements:

  • The structure must be like market_share.

  • The following columns must have a single value: sector, technology, region, scenario_source.

  • (Optional) If present, the column label is used for data labels.

convert_label

A symbol. The unquoted name of a function to apply to y-axis labels. For example:

  • To convert labels to uppercase use convert_label = toupper.

  • To get the default behavior of `

span_5yr

Logical. Use TRUE to restrict the time span to 5 years from the start year (the default behavior of qplot_trajectory()), or use FALSE to impose no restriction.

value_col

Character. Name of the column to be used as a value to be plotted.

Value

A data-frame ready to be plotted using plot_trajectory().

market_share.

Examples

# `data` must meet documented "Requirements"
data <- subset(
  market_share,
  sector == "power" &
    technology == "renewablescap" &
    region == "global" &
    scenario_source == "demo_2020"
)
