我使用以下代码绘制它并获得绘图

ggplot(ph, aes(x=factor(X2), y=res)) + 
  geom_hline(yintercept = -6:2, color="grey") +
  geom_boxplot(aes(fill=factor(model))) + 
  opts(axis.text.x = theme_text(angle = 45)) +
  geom_point()

在此处输入图像描述

如果我正确理解所有点应沿绿色条显示。为什么蓝条上方多了一个点？数据有问题？我无法理解。我有很多这样的图，其中一些点位于红色或蓝色条的下方或上方。

我想获得：1）所有点都沿着中央绿色条，或2）点沿着它们对应的条（因此模型1的点沿着模型1条等等）

更新：我有一个猜测 - 这可能是一个异常点，它会自动显示。

是的，这是一个异常值。我应该早点猜到。

这是一个解决方案。也许它对某人有用。

ggplot(ph, aes(x=factor(X2), y=res)) + 
  geom_hline(yintercept = -6:2, color="grey") +
  geom_boxplot(aes(fill=factor(model)), outlier.size=NA) + 
  opts(axis.text.x = theme_text(angle = 45)) +
  geom_point()

如果你geom_point()从你的情节中删除，你会看到，这些确实是异常值（正如你所怀疑的那样），它们被描述为每个点?geom_boxplot。

除了箱线图之外，您为什么要描绘所有数据点超出了我的范围。

r - 箱线图上点的位置
