如何创建带状图,其均值表示为短线而不是 R 中的点?

How can I create a stripchart with mean represented as a short line instead of dot in R?

我想创建一个如下所示的带状图:

但我只能使用 stat_summary 横杆创建类似的东西:

ggplot(data, aes(x=variable, y=value)) + 
stat_summary(fun.data="mean_sdl", fun.args = list(mult=1), geom="crossbar", width=0.5) +
geom_jitter(position=position_jitter(0.2))

结果是这样的:

如有任何关于如何修改代码的建议,我将不胜感激,这样我就可以获得第一张图片中的图表。

您可以使用 beeswarm 软件包:

library (beeswarm)

beeswarm(len ~ dose, data = ToothGrowth, 
    col = 4, pch = 16,
    main = 'beeswarm + bxplot')
  bxplot(len ~ dose, data = ToothGrowth, add = TRUE)

ggplot(mtcars, aes(factor(cyl), qsec)) +
    geom_jitter(position = position_jitter(width = 0.2)) +
    stat_summary(fun.data = 'mean_sdl', geom = 'errorbar', width = 0.3) +
    stat_summary(fun.y = mean, geom = 'point', size = 20, shape = '_')
