带有预计算值的 geom_boxplot [英] geom_boxplot with precomputed values

问题描述

过去，我已经能够使用 ggplot2 创建箱线图，方法是提供下须、下分位数、中位数、上分位数和上须以及 x 轴标签.例如:

In the past, I have been able to create boxplots using ggplot2 by providing the lower whisker, lower quantile, median, upper quantile, and upper whisker along with x-axis labels. For example:

DF <- data.frame(x=c("A","B"), min=c(1,2), low=c(2,3), mid=c(3,4), top=c(4,5), max=c(5,6))
ggplot(DF, aes(x=x, y=c(min,low,mid,top,max))) +
geom_boxplot()

将为两组数据(A 和 B)制作箱线图.这不再适用于我.我收到以下错误:

would make a boxplot for two sets of data (A & B). This no longer works for me. I get the following error:

Error: Aesthetics must either be length one, or the same length as the dataProblems:x

有谁知道 ggplot2 中是否有什么变化?

Does anyone know if something has been changed in ggplot2?

推荐答案

这适用于 ggplot2 版本 0.9.1(和 R 2.15.0)

This works using ggplot2 version 0.9.1 (and R 2.15.0)

library(ggplot2)

DF <- data.frame(x=c("A","B"), min=c(1,2), low=c(2,3), mid=c(3,4), top=c(4,5), max=c(5,6))

ggplot(DF, aes(x=x, ymin = min, lower = low, middle = mid, upper = top, ymax = max)) +
  geom_boxplot(stat = "identity")
