geom_boxplot中的宽度参数和stat ='identity' [英] Width parameter and stat = 'identity' in geom_boxplot
问题描述
我的问题基本上是
如果将 width = 0.1
移到 aes
之外,则会收到警告,并且宽度不会不变改变.
来自相关帖子的评论 ggplot-汇总统计信息中boxplot的宽度[重复] 建议并非总是如此.
样本数据
DF<-data.frame(x = c("2012","2016"),最小值= c(29.9,37.0),低= c(64.0,58.0),中= c(108.0,73.0),顶部= c(168.0,108.0),最大值= c(258.0,199.0))
My question is basically a duplicate of
Width of boxplot created from summary stats which has only received poor attention because of incomplete tagging (no r
nor ggplot2
tag), I have suggested some edits accordingly.
I tried to reproduce the example of this question, and I got
Warning: Ignoring unknown parameters: width
I found this fairly curious, as I have used width
as a parameter before. The warning disappeared when removing stat = identity
In plenty of previous threads, this parameter seemed to have worked (e.g.: Fine tuning ggplot2's geom boxplot). Is this related to the upgrade to ggplot2 3.0?
of note
I don't really want to use pre-computed values for box plots, I just came across this issue when starting to answer the above mentioned question.

I can confirm this (odd?) behaviour.
For example, if we do
ggplot(DF) +
geom_boxplot(
aes(x = x, ymin = min, lower = low, middle = mid, upper = top, ymax = max, width = 0.1),
stat = "identity", fill = "cornflowerblue")
we get a warning
Warning: Ignoring unknown aesthetics: width
but it actually does change the width
If you move the width = 0.1
outside of aes
you get a warning and the width does not change.
Comments from a related post ggplot - width of boxplot from summary stats [duplicate] suggest that this wasn't always the case.
Sample data
DF <- data.frame(
x = c("2012","2016"),
min = c(29.9,37.0),
low = c(64.0,58.0),
mid = c(108.0,73.0),
top = c(168.0,108.0),
max = c(258.0,199.0))
