如何在 R 中生成与此类似的抖动图? [英] How to generate a jitterplot similar to this one in R?

问题描述

我想在 R 中重现一个类似于 Zack 等人，Nature Genetics，2013 年的图 1a 中描述的抖动图:

I want to reproduce a jitterplot in R similar to the one described in Figure 1a of Zack et al., Nature Genetics, 2013:

我尝试了 beeswarm functino 和海盗功能.beeswarm 函数将点排成直线，它们看起来像一条线.我还尝试了 Pirateplot 函数，我通常喜欢它，但是，我没有弄清楚如何根据参考论文中的绘图中在 y 轴上的值来更改不同点的颜色.

I tried the beeswarm functino and the pirate function. The beeswarm function lines the points up to straight and they look like a line has been drawn. I also tried the Pirateplot function and I generally like it, however, I did not figure out how to change the color of different points based on their value on the y-axis as done in the plot from the reference paper.

最终，这些点应该像海盗图一样分散，但根据它们在 y 轴上的值进行颜色编码.

Eventually, the points should be scattered like in the pirate plot, but colorcoded according to their value on the y-axis.

大家有什么建议吗?

谢谢汤姆

推荐答案

我认为 ggplot2 是创建抖动图的最佳软件包.

I think ggplot2 is the best package to create a jitter plot.

ids <- c(
  rep("id1", 20), 
  rep("id2", 20), 
  rep("id3", 20)
)

values <- runif(60)

classes <- c(
  rep("class1", 30), 
  rep("class2", 30)
)

data <- data.frame(ids, values, classes)

library(ggplot2)

ggplot(data) +
  geom_jitter(
    aes(ids, values, color = classes), 
    width = 0.1
  )
