Details

plot_carbon invisibly returns a ggplot2 object with a pre-defined carbon dioxide chart using data from get_carbon. By default the chart is also displayed. Users may further modify the output ggplot2 chart.

Examples

# \donttest{
# Fetch carbon dioxide data:
maunaloa <- get_carbon()
#
# Plot output using package's built-in ggplot2 defaults
plot_carbon(maunaloa)

# Or just call plot_carbon(), which defaults to get_carbon() dataset
plot_carbon()

p <- plot_carbon(maunaloa, print = FALSE)
# Modify plot such as: p + ggplot2::labs(title='The Keeling Curve') # }
