在 facet_grid 图中，是否有一种方法可以将 facet strip 名称（y 轴交换）绘制在 y 轴名称的外部？

Question

我创建了一个分面绘图（使用ggplot2 :: facet_grid），其中我交换了y轴，使y条带文本绘制在图的左侧，并已经使用theme(strip.placement = "outside")将条带文本放置在y轴值之外。然而，条纹标题被绘制在y轴名称和y轴值之间。我想将条带文本绘制在y轴名称之外，以便y轴名称就直接绘制在y轴值旁边。是否可能实现？

这是我的一部分数据：

                                "6", "7 - 14", "7 - 14", "7 - 14", "7 - 14", "0", "1", "2", 
                                "3", "4", "5", "6", "7 - 14", "7 - 14", "7 - 14", "7 - 14", 
                                "7 - 14", "7 - 14", "0", "1", "2", "3", "4", "5", "6", "7 - 14", 
                                "7 - 14", "7 - 14", "7 - 14", "7 - 14")), row.names = c(NA, 
                                                                                        -379L), class = c("tbl_df", "tbl", "data.frame"))

这是我用来构建图表的代码。

library(ggplot2)
library(lemon)

ggplot(df,aes(x = month, 
                   y = perc,
                   fill = category)) +
  geom_col(position = "fill") +
  facet_rep_grid(place ~ year , 
                 repeat.tick.labels = T,
                 switch = "y") +
  theme_minimal() + 
  theme(strip.text.y = element_text(angle = 180),
        strip.placement = "outside")

下面是生成的图形：

最终，这是期望的图形：

Answer 1

我认为在ggplot2中没有这样的方法，但可以使用其他附加包来实现。

library(ggplot2)
library(lemon)
library(cowplot)
library(grid)

g <- ggplot(df,aes(x = month, 
                   y = perc,
                   fill = category)) +
     geom_col(position = "fill") +
     facet_rep_grid(place ~ year ,
                repeat.tick.labels = T) +
     theme_minimal() + 
     theme(strip.text.y = element_blank())

a <- textGrob('Site 1', gp=gpar(fontsize=10))
b <- textGrob('Site 2', gp=gpar(fontsize=10))

plot_grid(plot_grid(a, b, ncol = 1), g, rel_widths = c(0.1, 1))

Answer 2

我发现一种更直接的方法（重新定位轴标题，而不是构建和放置新条目）：

#   as above but with ...
+ theme(strip.text.y = element_text(angle = 180), 
      axis.title.y = element_text(vjust = -10),  # value by experiment
      strip.placement = "outside")

vjust参数是相对于y轴标题方向的。使用hjust可以上下移动它。我猜这是以“点”为单位的。在我看来，hjust值是以“upc”为单位解释的。
