Download and plot essential climate data — emissions

Plots a treemap of cumulative co2 emissions by country since 1900.

Usage

emissions_map(
  dataset = get_emissions(),
  print = TRUE,
  since = 1900,
  number = "all",
  title = substitute(paste(since, "-", to, " Cumulative " * CO[2] *
    " Emissions by Country"), list(since = since, to =
    as.character(dataset[nrow(dataset), 2])))
)

Arguments

dataset: Name of the tibble generated by get_emissions
print: (boolean) Display emissions treemap, defaults to TRUE. Use FALSE to not display chart.
since: (numeric) Start year for cumulative emissions, defaults to 1900 if omitted
number: (numeric) Number of countries to display in treemap, defaults to all if omitted
title: (string) Manually specify chart title

Value

Invisibly returns a ggplot2 object with emissions treemap

Details

emissions_map invisibly returns a ggplot2 object with cumulative emissions treemap by country since 1900 from get_emissions. By default the chart is also displayed. Users may further modify the output ggplot2 chart.
