R小提琴圖和箱形圖一起使填充表現出不同的箱形圖

Question

好的，所以我想把小提琴情節和白色的盒子圖一起繪制，但我的數據有點棘手。 我將data.frame中的數據與多個列融合，每個列的值都對應於兩個級別的因子，這里是我的數據的近似值：

library(ggplot2)
library(reshape2)

dat <- list(
  A = rbind(
    data.frame(group = "1",
               vals = rnorm(500)),
    data.frame(group = "2",
               vals = rnorm(100))
  ),
  B = rbind(
    data.frame(group = "1",
               vals = rnorm(500)),
    data.frame(group = "2",
               vals = rnorm(100))
  ),
  C = rbind(
    data.frame(group = "1",
               vals = rnorm(500)),
    data.frame(group = "2",
               vals = rnorm(100))
  )
)

dat.melt <- melt(dat)

我能找到的最好的是手動設置填充，但它會影響小提琴圖和箱形圖：

dodge <- position_dodge(width = 1)

p <- ggplot(dat.melt, aes(x = L1, y = value, fill = group))+
  geom_violin(position = dodge)+
  geom_boxplot(width = 0.3,
                 position = dodge,
                 outlier.shape = NA)+
  scale_fill_manual(values=c("white", "white"))

我可以只制作白色的箱形圖而不是小提琴嗎？

PS我怎樣才能為小提琴制作傳說而不顯示箱形圖？

Answer 1

試試這個：

p <- ggplot(dat.melt, aes(x = L1, y = value)) +
  geom_violin(aes(fill = group), position = dodge) +
  geom_boxplot(aes(group=interaction(group,L1)), 
            width=0.3, fill="white", position=dodge,
            outlier.shape=NA)
print(p)

Answer 2

你也可以試試這個：

ggplot(dat.melt, aes(x = L1, y = value, fill=group))+
  geom_violin(position = position_dodge(width = 1)) +
  geom_boxplot(data = dat.melt, 
               aes(x = L1, y = value, col=group), fill="white", 
               position = position_dodge(width = 1), width=0.3,outlier.shape=NA)+
  geom_boxplot(position = position_dodge(width = 1), alpha=0, width=0.3)
