ggdaynight is an R package that adds a day/night pattern to ggplot2 plots. Daytime is represented by rectangles filled with a specified day_fill color and nighttime by rectangles filled with a specified night_fill color. The pattern is created along the x-axis, which must be a datetime variable.
You can install the released version of ggdaynight from CRAN:
install.packages("ggdaynight")You can install the development version of ggdaynight from GitHub with:
# Install devtools if not already installed
if (!requireNamespace("devtools", quietly = TRUE)) {
