R语言删除除最小值和最大值外的所有离群值; ggplot2

我已经融化了一个数据集，并制作了一个ggplot箱线图。

dfplot.m <- melt(dataforplotscaled, id.var = "NameNum")
p <- ggplot(data = dfplot.m, aes(x=variable, y=value)) + geom_boxplot(aes(fill = as.factor(NameNum)),outlier.colour = 'black')

所以它看起来像这样：

我可以通过将outlier.colour设置为FALSE来删除离群值。但是，是否可以删除除变量的单个最大值和单个最小值之外的所有离群值？谢谢

dput(dfplot.m[sample(1:nrow(dfplot.m), 100, replace=FALSE), ])
structure(list(NameNum = c(1, 2, 1, 1, 1, 1, 1, 2, 2, 2, 1, 1,

下面是我将如何使用您提供的数据集来完成此操作。
首先，让我们得到一个数据集，其中只有每个因子组合的最小值和最大值：

library(dplyr)
dat2<- dfplot.m %>% group_by(variable, NameNum) %>%
                    arrange(value) %>%
                    slice(c(1, n()))

然后使用geom_point绘制这些点：

library(ggplot2)
ggplot(data = dfplot.m, aes(x = variable, y = value)) +
   geom_boxplot(aes(fill = as.factor(NameNum)),outlier.colour = 'black') +
   geom_point(data = dat2, aes(fill = as.factor(NameNum)), position = position_dodge(0.75))

如果你不想让刻痕（线）比正常的长，使用这个：

dat <-  mtcars

require(data.table)
ext <- melt(setDT(dat)[, range(wt), cyl], "cyl")

ext$cyl <- as.factor(ext$cyl)
dat$cyl <- as.factor(dat$cyl)

require(ggplot2)
ggplot(dat, aes(cyl, wt)) + geom_boxplot(outlier.size = 0) +
  geom_point(data = ext, aes(x = cyl, y = value))

也就是说

而不是：

ggplot(dat, aes(cyl, wt)) + geom_boxplot()

如果要移动图形上的点以使其与所需的箱线图对齐，可以使用position = position_nudge（x = -0.1），并根据点的显示位置将0.1更改为其他值
