In ggChinaFlag: Drawing Chinese National and Historical Flags with 'ggplot2'

Plot the Blue Sky, White Sun, and a Wholly Red Earth flag

Description

Programmatically draws the Blue Sky, White Sun, and a Wholly Red Earth flag used during the Nationalist Government period (1928-1949) of the Republic of China, using analytic geometry with ggplot2 and ggforce. The flag has a red field, a blue canton in the upper-left, and a twelve-rayed white sun within the canton, all generated from vector geometry without external image files.

Usage

plot_ROC_KMT_flag(label = TRUE)

Arguments

label

Logical; whether to display the title and explanatory text. TRUE (default) shows the title, designer and period; FALSE draws only the flag.

Details

• The red field and blue canton are built from rectangles.

• The twelve-rayed sun is a closed polygon of 24 vertices.

• Two concentric circles form the core of the white sun.

• ggplot2::coord_quickmap() keeps the proportions undistorted.

• Axes, grid and legend are hidden by default.

Value

A ggplot object, which can be printed or saved with ggsave().
