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:

Adds a day/night pattern to a ggplot object.
day_fill: The fill color for daytime rectangles. Defaults to "white".night_fill: The fill color for nighttime rectangles. Defaults to "grey30".sunrise: The hour at which daytime starts. Defaults to 6 (6 AM).sunset: The hour at which nighttime starts. Defaults to 18 (6 PM)....: Additional arguments passed to geom_rect.A ggplot2 layer representing the day/night pattern.
