Examples

# Fetch methane data:
ch4 <- get_methane()
#
# Plot output using package's built-in ggplot2 defaults
plot_methane(ch4)

# Or just call plot_methane(), which defaults to get_methane() dataset
plot_methane()

p <- plot_methane(ch4, print = FALSE)
# Modify plot such as: p + ggplot2::labs(title='Trend in Atmospheric Methane')
