有序和排序的ggplot条形图

Question

我正在尝试根据我的数据集创建 'Treatment' 和 'Day' 之间交互的条形图。我希望 'Treatment' 按以下顺序排序：'Before'、'During' 和 'After' 我还希望 'Day' 1 和 2 'Before'、'During' 和 'After' 彼此相邻，而不是将每个 'Day' 组合在一起。这是我的数据集：

structure(list(Name = structure(c(9L, 9L, 5L, 5L, 14L, 14L, 15L, 
15L, 1L, 1L, 7L, 7L, 12L, 12L, 2L, 2L, 11L, 11L, 16L, 16L, 13L, 
13L, 6L, 6L, 8L, 8L, 3L, 3L, 4L, 4L, 10L, 10L, 9L, 9L, 5L, 5L, 
14L, 14L, 15L, 15L, 1L, 1L, 7L, 7L, 12L, 12L, 2L, 2L, 11L, 11L,

"Treatment", "Behavior"), class = "data.frame", row.names = c(NA, 
-96L))

这是我用来生成当前图形的脚本：

   ggplot(perch1, aes(x = interaction(Treatment,Day), y = Behavior, fill =  factor(Day)))

Answer 1

一个选项是向 data.frame 添加一个新列并手动指定级别的顺序，而不是乱用 interaction：

library(ggplot2)
##
df$Group <- factor(
  paste0(df$Day," : ",df$Treatment),
  paste0(rep(1:2,3)," : ",
         rep(c("Before","During","After"),each=2)))
##
R> ggplot(
    df, 
    aes(x=Group, 
        y=Behavior, 
        fill=factor(Day)))+
    geom_bar(stat='identity')+
    scale_x_discrete(
      labels=paste0("Day ",levels(df$Group)))

Answer 2

另一种方法是使用小平面包裹在单独的面板中绘制每个处理。

ggplot(df, aes(x = factor(Day), y = Behavior, fill = factor(Day))) + 
       geom_bar(stat = 'identity') + facet_wrap(~Treatment, nrow = 1)

这不会在 X-axis 上标记您的互动，而是将其放在面板标题中。
