The goal of r2dii.plot is to help you plot 2DII data in an informative, beautiful, and easy way.


You can install the released version of r2dii.plot from CRAN with:


And the development version from GitHub with:

# install.packages("devtools")


The r2dii.plot package is designed to work smoothly with other “r2dii” packages –, r2dii.match, and r2dii.analysis. It also plays well with the ggplot2 package, which helps you customize your plots. Here, we’ll use an example data set that comes with r2dii.plot and that resembles the output of the target_market_share() function in the r2dii.analysis package.

library(ggplot2, warn.conflicts = FALSE)
library(dplyr, warn.conflicts = FALSE)

Plot trajectory chart

  • Use qplot_*() to quickly get a plot with standard titles and labels.
# `data` must meet documented "Requirements"
data <- market_share %>%
    sector == "power",
    technology == "renewablescap",
    region == "global",
    scenario_source == "demo_2020"


  • Use plot_*() for a more “bare” plot that you can customize yourself by modifying the input data and applying ggplot2 functions.
data <- market_share %>%
    sector == "power",
    technology == "renewablescap",
    region == "global",
    scenario_source == "demo_2020",
    between(year, 2020, 2035)
  ) %>%
    label = case_when(
      metric == "projected" ~ "Your Portfolio",
      metric == "corporate_economy" ~ "Benchmark (Corp. Econ.)",
      metric == "target_sds" ~ "SDS Scenario",
      metric == "target_sps" ~ "SPS Scenario",
      metric == "target_cps" ~ "CPS Scenario",
      TRUE ~ metric

plot_trajectory(data) +
    title = "Power production trajectory for Renewables",
    subtitle = "With reference to climate scenarios.",
    x = "Year",
    y = "Production (normalized to 2020)"
#> Warning: The `data` argument of `plot_trajectory()` must be prepped already as of r2dii.plot 0.4.0.
#> • From the next release you will need to call `r2dii.plot::plot_trajectory(data)`
#> prior to calling `r2dii.plot::plot_trajectory()`.
#> • Alternatively custom data preparation will also become possible.
