Download and plot essential climate data

Description

Plots the Common Era 2000-year global temperature anomaly retrieved using get_temp2k() with ggplot2. The output ggplot2 object may be further modified.

Usage

plot_temp2k(
  dataset = get_temp2k(),
  instrumental = TRUE,
  filtered = TRUE,
  print = TRUE
)

Arguments

dataset	Name of the tibble generated by get_temp2k
instrumental	(boolean) Include the Cowtan & Way instrumental temperatures through 2017. Defaults to TRUE.
filtered	(boolean) Use the filtered temperatures provided by PAGES2k Consortium. Temperatures filtered using a 31-year Butterworth filter. Defaults to TRUE.
print	(boolean) Display temperature anomaly ggplot2 chart, defaults to TRUE. Use FALSE to not display chart.

Details

plot_temp2k invisibly returns a ggplot2 object with a pre-defined temperature anomaly chart using data from get_temp2k. By default the chart is also displayed. Users may further modify the output ggplot2 chart.

Value

Invisibly returns a ggplot2 object with temperature anomaly chart

Examples

# Fetch temperature anomaly:
anomaly <- get_temp2k()
#
# Plot output using package's built-in ggplot2 defaults
plot_temp2k(anomaly)

# Or just call plot_temp2k(), which defaults to get_temp2k() dataset
plot_temp2k()

p <- plot_temp2k(anomaly, print = FALSE)
# Modify plot such as: p + ggplot2::labs(title='Temperature Increase in the Common Era')
