R.Y 间隔(刻度线)和网格中的箱线图

Boxplots in R. Y interval (tick marks) and grid

我有以下代码:

  boxplot(c(Scatt_nocoop, Scatt_coop), 
          xlab="Scattered", col=c("red","red"), 
          names=c("Non-cooperative"," Cooperative "), 
          ylim = c(0,2.5))

我正在尝试每隔 0.1 在 Y 轴上添加刻度线,然后添加一个网格。

另外,我想得到 Y 轴的百分比而不是数字。

谢谢!

不确定您的数据是什么样的,但我猜您想要这样的数据:

x1 <- rnorm(100) + 2

x2 <- rnorm(100) + 2

df <- data.frame(x = c(x1, x2), g = rep(1:2,each=100))

boxplot(df$x~df$g, 
        xlab="Scattered", col=c("red","red"), 
        names=c("Non-cooperative"," Cooperative "), 
        ylim = c(0,5),
        yaxt = "n")

添加刻度和(手动)网格线

axis(2, at = seq(0,5,0.1))
lapply(seq(0,5,0.1), function(x) abline(a = x,b = 0))
