ggplot：geom_boxplot和geom_jitter

Question

將數據點與箱形圖對齊。

數據：

data<-structure(list(score = c(0.058, 0.21, -0.111, -0.103, 0.051, 
0.624, -0.023, 0.01, 0.033, -0.815, -0.505, -0.863, -0.736, -0.971, 
-0.137, -0.654, -0.689, -0.126), clin = structure(c(1L, 1L, 1L, 
1L, 1L, 2L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 1L, 2L, 2L, 1L), .Label = 
c("Non-Sensitive", 
"Sensitive "), class = "factor"), culture = structure(c(1L, 1L, 
1L, 1L, 1L, 1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L
), .Label = c("Co-culture", "Mono-culture"), class = "factor"), 
    status = structure(c(2L, 2L, 1L, 2L, 2L, 1L, 2L, 2L, 1L, 
    2L, 2L, 1L, 2L, 2L, 1L, 2L, 1L, 2L), .Label = c("new", "old"
    ), class = "factor")), .Names = c("score", "clin", "culture", 
"status"), class = "data.frame", row.names = c(NA, -18L))

碼：

p<-ggplot(data, aes(culture, as.numeric(score),fill=status))

p+geom_boxplot(outlier.shape = NA)+
   theme_bw()+scale_fill_grey(start = 0.8, end = 1)+
   labs(title="title", x="", y="score",fill="", colour="")+
   geom_jitter(aes(colour = clin), alpha=0.9, 
   position=position_jitter(w=0.1,h=0.1))

如您所見，使用geom_jitter繪制的數據點與箱線圖不對齊。 我知道我也需要向geom_jitter提供aes元素-但我不確定如何正確地做到這一點。

Answer 1

我不認為您可以這樣做，因為盒形圖的位置是由躲閃算法驅動的，而不是由外在的美感決定的，盡管我很好奇是否有人想辦法。 這是一種解決方法：

p<-ggplot(data, aes(status, as.numeric(score),fill=status))
p+geom_boxplot(outlier.shape = NA)+
  theme_bw()+scale_fill_grey(start = 0.8, end = 1)+
  labs(title="title", x="", y="score",fill="", colour="")+
  geom_jitter(aes(colour = clin), alpha=0.9, 
              position=position_jitter(w=0.1,h=0.1)) +
  facet_wrap(~ culture)

通過使用culture方面，我們可以為status賦予明確的美感，然后使geom_jitter與geom_boxplot 。 希望這足夠接近您的目的。
