gridExtra 2.0.0 更改标题大小 [英] gridExtra 2.0.0 change title size

问题描述

我知道 gridExtra 已更新.结果，我想知道如何更改标题大小.这不再有效

I know that gridExtra has been updated. As a result, I'm left wondering how to change title sizes. This no longer works

   grid.arrange(a, b, c, d,ncol=2, 
      nrow=2, main=textGrob("Title", gp=gpar(fontsize=15,font=8)))

这不再有效，主要选项已更改为顶部，但我无法弄清楚 textGrob 功能来改变字体大小).有什么线索吗?谢谢

That no longer works, the option for main has been changed to top but I can't figure out the textGrob features to alter the font size). Any clues? Thanks

推荐答案

首先，使用 library() 或 require()<导入包 grid/代码>.其次，将代码中的 main 更改为 top.

First, import the package grid with either library() or require(). Second, change main to top in your code.

见下文:

library(grid)

 grid.arrange(a, b, c, d,ncol=2, 
     nrow=2, top=textGrob("Title", gp=gpar(fontsize=15,font=8)))

我在使用 gridExtra v2.0.0 时遇到了类似的问题，收到以下错误:

I ran into a similar issue with gridExtra v2.0.0, receiving the following error:

arrangeGrob(...) 中的错误:找不到函数textGrob"

Error in arrangeGrob(...) : could not find function "textGrob"

表示网格没有作为 gridExtra 的依赖项加载.我通过要求或导入库 grid 解决了这个问题:require(grid) 或 library(grid).

indicating that grid wasn't loaded as a dependency for gridExtra. I resolved it by requiring or importing the library grid by either:require(grid) or library(grid).

希望有所帮助.
