快速绘制发表级图片ggplot2智能版ggpubr包学习总结

发表于 | 分类于

软件简介

Hadley Wickham编写的ggplot2是出色且灵活的作图软件包，可用于R中的优雅数据可视化。ggplot2默认生成的绘图需要进行一些格式化，才能作出发表级别的图片质量。另外，要自定义使用ggplot，但其语法是不透明的，这对没有熟练R编程技能的用户增加了难度。“ ggpubr”软件包提供了一些易于使用的功能，用于创建和自定义基于“ ggplot2”的图片绘制。
ggpubr包的主要特点：

  • ggplot2软件包周围的包装，对于R编程的初学者来说，语法不太透明。
  • 使用非高级R编程技能帮助研究人员轻松创建可随时发布的图。
  • 可以将p值和显着性水平自动添加到箱形图，条形图，折线图等中。
  • 使在同一页面上排列和注释多个图变得容易。
  • 使更改颜色和标签等图形参数变得容易。
