r - 如何根据ggplot/R中的不同数据源将不同的箱线图添加到同一图中？

请在下面找到 My Data。请注意，下图是我希望复制的设计示例，与 My Data 没有特别关联。
My Data 存储在 p 中。我有一个连续的协变量 p$ki67pro，它指定肿瘤样本中活跃 split 的细胞百分比(因此，范围从 0 到 100)。我有肿瘤的三个不同阶段，对应于 p$WHO.Grade==1,2,3 。每个样本代表一个有复发( p$recurrence==1 )或没有( p$recurrence==0 )复发的肿瘤患者。

所以:

head(p)
   WHO.Grade recurrence ki67pro
1          1          0       1
2          2          0      12
3          1          0       3
9          1          0       3
10         1          0       5
11         1          0       3

我希望生成下面的箱线图。如您所见，有四个点对应于每个 p$WHO.Grade 和 All samples 。每个 p$WHO.Grade + All 有两个箱线图。

r - 如何根据ggplot/R中的不同数据源将不同的箱线图添加到同一图中？-LMLPHP

根据 p$WHO.Grade 和 All ，我想要一个箱线图代表复发性肿瘤的 p$ki67pro ( p$recurrence==1 )，另一个箱线图代表非复发性肿瘤的 p$ki67pro ( p$recurrence==0 )。

IE。
p$ki67pro[p$WHO.Grade==1 & p$recurrence==0] 与
p$ki67pro[p$WHO.Grade==1 & p$recurrence==1]p$ki67pro[p$WHO.Grade==2 & p$recurrence==0] 与
p$ki67pro[p$WHO.Grade==2 & p$recurrence==1]p$ki67pro[p$WHO.Grade==3 & p$recurrence==0] 与
p$ki67pro[p$WHO.Grade==3 & p$recurrence==1]
对于 Allp$ki67pro[p$recurrence==0] 与p$ki67pro[p$recurrence==1]
到目前为止，我已经使用了以下脚本，但我可以弄清楚如何包含 All。请注意，只有一种情况 p$WHO.Grade==3

df <- data.frame(x = as.factor(c(p$WHO.Grade)),
                 y = c(p$ki67pro),
                 f = rep(c("ki67pro"), c(nrow(p))))

df <- df[!is.na(df$x),]
ggplot(df) +
  geom_boxplot(aes(x, y, fill = f, colour = f), outlier.alpha = 0, position = position_dodge(width = 0.78)) +
  scale_x_discrete(name = "", label=c("WHO-I","WHO-II","WHO-III","All")) +
  scale_y_continuous(name="x", breaks=seq(0,30,5), limits=c(0,30)) +
  stat_boxplot(aes(x, y, colour = f), geom = "errorbar", width = 0.3,position = position_dodge(0.7753)) +
  geom_point(aes(x, y, fill = f, colour = f), size = 3, shape = 21, position = position_jitterdodge()) +
  scale_fill_manual(values = c("#edf1f9", "#fcebeb"), name = "",
                    labels = c("", "")) +
  scale_colour_manual(values = c("#1C73C2", "red"), name = "",
                      labels = c("","")) + theme(legend.position="none")

最佳答案

可以使用的一个技巧是在 WHO.Grade 中创建一个新级别，因为它只有 3 个级别。这应该是一个临时级别，所以一个很好的方法是使用包 dplyr ，函数 mutate 。

请注意，无需创建新的数据帧 df 。

library(ggplot2)
library(dplyr)

p %>%
  bind_rows(p %>% mutate(WHO.Grade = 4)) %>%
  mutate(WHO.Grade = factor(WHO.Grade),
         recurrence = factor(recurrence)) %>%
  ggplot(aes(WHO.Grade, ki67pro,
             fill = recurrence, colour = recurrence)) +
  geom_boxplot(outlier.alpha = 0,
               position = position_dodge(width = 0.78, preserve = "single")) +
  geom_point(size = 3, shape = 21,
             position = position_jitterdodge()) +
  scale_x_discrete(name = "",
                   label = c("WHO-I","WHO-II","WHO-III","All")) +
  scale_y_continuous(name = "x", breaks=seq(0,30,5), limits=c(0,30)) +
  scale_fill_manual(values = c("#edf1f9", "#fcebeb"), name = "",
                    labels = c("", "")) +
  scale_colour_manual(values = c("#1C73C2", "red"), name = "",
                      labels = c("","")) +
  theme(legend.position="none")
