glydraw is a ggplot2-native R engine for drawing reproducible SNFG glycan cartoons from glycan structure objects or text notations, with support for batch export, structural highlighting, and deep appearance customization.
Installation
Install glycoverse
We recommend installing the meta-package glycoverse, which includes this package and other core glycoverse packages.
Install glydraw alone
If you don’t want to install all glycoverse packages, you can only install glydraw.
You can install the latest release of glydraw from r-universe (recommended):
# install.packages("pak")
pak::repo_add(glycoverse = "https://glycoverse.r-universe.dev")
pak::pkg_install("glydraw")Or from GitHub:
pak::pkg_install("glycoverse/glydraw@*release")Or install the development version (NOT recommended):
pak::pkg_install("glycoverse/glydraw")Note: Tips and troubleshooting for the meta-package glycoverse are also applicable here: Installation of glycoverse.
