r - 试图在 grid.arrange 和arrangeGrob 中平衡地块的底部。还试图移动 Y 轴标签
问题描述
我有 3 个地块,两个地块堆叠在一起,显示为一个地块。我做了一个并排(2 列)的图,所以它看起来像 2 个地块彼此相邻(尽管同样,一个地块实际上是两个地块堆叠在一起)。我有两个问题:
无论我尝试什么(vjust、缩放等),我都无法让两个并排的图的底部保持平衡。
我无法获得以堆叠图为中心的 Y 轴标签,因为您无法制作跨越两个图的标签。我已经尝试对整个面板使用“标题”,但是我无法更改字体大小以匹配其余标签。
我尝试过使用 vjust,为整个情节添加标题,改用 plot_grid,以及我能想到的所有其他内容。

解决方案
您可以使用该patchwork
包来布置图。有关布局系统如何工作的详细信息,请参阅 Vignette:
从 github 安装包:
devtools::install_github("thomasp85/patchwork")
然后,
library(patchwork)
{g.top + g.bottom + plot_layout(ncol=1)} - gg
