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) p + ggplot2::labs(title='The Keeling Curve') # }
