Overview

About

Maintained by Zhaoshuo LiuCRAN page ↗GitHub ↗Issues ↗

Provides programmatic implementations for drawing Chinese national and historical flags using analytic geometry and 'ggplot2'-based vector graphics. Flag designs are constructed entirely from geometric primitives such as polygons and rectangles, without relying on external image files. The package is intended for educational demonstration, reproducible visualization, and procedural graphics in R.

Changes in 1.0.0

First stable release.
plot_PLA() gains a new subtype, the flag of the China Armed Police Force (CAPF, 2018-), accessible via subtype = "武警", "CAPF", or "People's Armed Police Force". The lower 3/8 of the flag carries three dark olive-green stripes (each H/12 high with H/24 red gaps), constructed per the official flag image released by the Ministry of National Defense.
FlagStorage() and plotCNFlag() now recognise the CAPF flag in both Chinese ("中国人民武装警察部队旗") and English.
Added the package logo (hex sticker) in man/figures/logo.png, shown in the README and the pkgdown site.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)

install.packages("ggChinaFlag", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("XLions/ggChinaFlag")

Development version from XLions/ggChinaFlag. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-ggchinaflag

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-ggChinaFlag

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager
