如何在已经使用道奇时向geom_point添加抖动

Question

我在单个geom_points前面绘制汇总统计数据，但不知道如何将抖动添加到图中。我认为问题是，我已经使用位置参数将高低水点移开。

    waterSymPop_p <- ggplot(aes(x = SymPop, y = Finish, fill = Water, color = Water), data = xanFull) +
  geom_point(position = position_dodge(width = 0.9)) +
  stat_summary(fun.data = "mean_cl_normal", geom = "pointrange", position = position_dodge(width = 0.9)) +
  coord_flip()

下面是生成的情节(显然没有完成配色方案，等等)

​

我希望这一点在每一个点组内稍微抖动(即不成直线)。谢谢你的帮助！

答:使用position_jitterdodge

经修正的守则和新数字：

ggplot(aes(x = SymPop, y = Finish, fill = Water, color = Water), data = xanFull) +
  geom_point(position = position_jitterdodge(dodge.width = 0.9, jitter.width = 0.2)) +
  stat_summary(fun.data = "mean_cl_normal", geom = "pointrange", position = position_dodge(width = 0.9)) +
  coord_flip()
