R：ggplot2，我可以设置阴谋标题环绕并缩小文本以适应阴谋吗？ [英] R: ggplot2, can I set the plot title to wrap around and shrink the text to fit the plot?

问题描述

  library（ggplot2）
 
 my_title =这是一个很长的情节标题，我想很好地包装\\\
并适合情节而不必手动添加反斜杠n，但目前它不会
 
r < -  ggplot（data = cars，aes（x = speed，y = dist））
r + geom_smooth（）+＃（左）
 opts（title = my_title）
  

我们不认为有一个文字换行选项，我们不认为有文字换行选项在 ggplot2 中（我总是手动插入\\\
）。但是，您可以通过以下方式更改代码来缩小标题文本的大小：

  title.size<  - 10 
r + geom_smooth（）+ opts（title = my_title，plot.title = theme_text（size = title.size））
  

实际上，您可以通过 theme_text 函数实现文本的所有方面。

library(ggplot2)

my_title = "This is a really long title of a plot that I want to nicely wrap \n and fit onto the plot without having to manually add the backslash n, but at the moment it does not"

r <- ggplot(data = cars, aes(x = speed, y = dist))
r + geom_smooth() + #(left) 
opts(title = my_title)

can I set the plot title to wrap around and shrink the text to fit the plot?

解决方案

I do not think there is a text wrap option in ggplot2 (I have always just inserted \n manually). You can, however, shrink the size of the title's text by altering your code in the following way:

title.size<-10
r + geom_smooth() + opts(title = my_title,plot.title=theme_text(size=title.size))

In fact, you all aspects of text with the theme_text function.
