在 Q-Q 图中绘制红色十分位数 stat_qq() 或 geom_qq()
Ploting red deciles in Q-Q plot stat_qq() or geom_qq()
我正在尝试将分布与理论正态分布进行比较，但我想在 Q-Q 图中将小数分位数表示为红色。
这是我正在使用的数值数组（作为 df）。

如何将十分位数着色为红色？
首先使用 ntile 函数创建十分位数。之后，您可以通过过滤该数据并将它们着色为红色来为第一个十分位数着色。您可以使用以下代码：
library(tidyverse)
example <- example %>% mutate(decile = ntile(v1, 10))
ggplot() +
geom_qq(example, mapping = aes(sample=example$v1),col=ifelse(example$decile == 1, "red", "black")[order(example$v1)]) +
geom_qq_line(aes(sample=example$v1))
输出：
感谢@Quinten 的回答，我可以设法从 qq 积分中脱颖而出。所以我添加了 ntile() 函数并计算了变化点（实际十分位数），这就是解决方案：
library(tidyverse)
example <- example %>%
mutate(decile = ntile(v1, 10)) %>%
arrange(v1) %>%
mutate(difs = decile - lag(decile)) %>%
mutate(difs= ifelse(is.na(difs),1,difs))
example %>%
ggplot(aes(sample=v1)) +
geom_qq(col=ifelse(example$difs == 1, "red", "black"),
alpha=ifelse(example$difs == 1, 1, 0.33),
size=ifelse(example$difs == 1, 1.5, 1)) +
