关于《R语言绘图专栏》
关于**《R语言绘图专栏》,此专栏基于**<span class="ne-text">R语言</span>
绘制图形。每个图形我们会提供对应的 <span class="ne-text">R代码</span>
、<span class="ne-text">数据</span>
和 <span class="ne-text">文本</span>
文档。此系列将会是一个长期更新的系列。

Code
- 加载所需R包
library(ggrain)
library(ggplot2)
- 加载数据
iris
- 绘制基础云雨图
ggplot(iris, aes(x = Species, y = Sepal.Length, fill = Species)) +
geom_rain(rain.side = 'l')
ggplot(iris, aes(x = 1, y = Sepal.Length, fill = Species)) +
geom_rain(alpha = .5)
给散点添加颜色
ggplot(iris, aes(1, Sepal.Width, fill = Species, color = Species)) +
geom_rain(alpha = .6,
boxplot.args = list(color = "black", outlier.shape = NA)) +
theme_classic() +
scale_fill_brewer(palette = 'Dark2') +
scale_color_brewer(palette = 'Dark2')
将图形进行翻转,使用 <span class="ne-text">coord_flip()</span>
ggplot(iris, aes(Species, Sepal.Width, fill = Species)) +
geom_rain(alpha = .5) +
theme_classic() +
scale_fill_brewer(palette = 'Dark2') +
guides(fill = 'none', color = 'none') +
coord_flip()
- 两两进行配对,使用线条连线 事例数据整理

geom_rain(alpha = .5) +
theme_classic() +
scale_fill_manual(values=c("dodgerblue", "darkorange")) +
guides(fill = 'none', color = 'none')
