Plots the daily temperatures since 1940 and current anomaly data retrieved using get_dailytemp() with ggplot2. The output ggplot2 object may be further modified.
Usage
plot_dailytemp(
dataset = get_dailytemp(),
print = TRUE,
anomaly = FALSE,
maxtemp = FALSE,
current_year = as.numeric(substr(Sys.Date(), 1, 4)),
title_lab = "Daily Average Air Temperature"
)Arguments
- dataset
Name of the tibble generated by
get_dailytemp(boolean) Display daily temperature ggplot2 chart, defaults to TRUE. Use FALSE to not display chart.
- anomaly
(boolean) Display current anomaly versus historic mean, defaults to TRUE.
- maxtemp
(boolean) Display current deviation versus historic max, defaults to FALSE.
- current_year
(numeric) Year to highlight in alternate color, defaults to current year.
- title_lab
(string) Title to override default chart title. Default title pulls region name from dataset attributes.
Details
plot_temp invisibly returns a ggplot2 object with a pre-defined daily temperature anomaly chart using data from get_dailytemp.
By default the chart is also displayed. Plots one line per year, as well as mean and anomaly (which may be disabled). Users may further modify the output ggplot2 chart.

Examples
# \donttest{
# Fetch temperature anomaly:
dailydata <- get_dailytemp()
#
# Plot output using package's built-in ggplot2 defaults
plot_dailytemp(dailydata)
# Don't plot anomaly shading and highight specific year
plot_dailytemp(anomaly = FALSE, current_year = 2012)
# Or just call plot_temp(), which defaults to get_temp() dataset
plot_dailytemp()
p <- plot_dailytemp(dailydata, print = FALSE)
# Modify plot such as: p + ggplot2::labs(title='Record Temperatures in 2023') # }
