Examples
# \donttest{
# Fetch from cache if available:
emissions <- get_emissions()
#
# Force cache refresh:
emissions <- get_emissions(use_cache=FALSE)
#
# Review cache contents and last update dates:
hockeystick_cache_details()
#> <hockeystick cached files>
#> directory: /home/runner/.cache/R/hockeystick

#
# Plot output using package's built-in ggplot2 settings
plot_emissions(emissions) # }
