Plots the Vostok ice core data retrieved using get_paleo()
with ggplot2. The output ggplot2 object may be further modified.
Usage
plot_paleo(dataset = get_paleo(), print = TRUE)
Details
plot_paleo
invisibly returns a ggplot2 object with a pre-defined Vostok ice core chart using data from get_paleo
.
The returned chart stacks carbon dioxide concentration over temperature over 420,000 years.
By default the chart is also displayed. Users may further modify the output ggplot2 chart.

Examples
# \donttest{
# Fetch Vostok data:
vostok <- get_paleo()
#> Retrieving remote data requires internet connectivity.
#
# Plot output using package's built-in ggplot2 defaults
plot_paleo(vostok)
# Or just call plot_paleo(), which defaults to get_paleo() dataset
plot_paleo()
#> Retrieving remote data requires internet connectivity.
p <- plot_paleo(vostok, print = FALSE)
# Modify plot such as: p + patchwork::plot_annotation(title='A Long History of Carbon') # }
