在ggplot中添加默认标签 [英] Add default label in ggplot

问题描述

我想为所有图表添加一个默认标题，这样我就不必为我制作的所有图表输入默认标题.有没有一种方法可以将默认文本标签添加到主题?

I would like to add a default caption to all my charts so that I do not have to type it in for all the charts I make. Is there a way to add default text labels to a theme?

这就是我想要做的.我正在使用自己的主题(在本示例中为 theme_bw ).我想避免每次制作图表时都输入标题.有没有办法在 theme_bw()内添加 + labs(标题=默认")?

Here's what I'd like to do. I'm using my own theme (theme_bw in this example). I would like to avoid typing the caption every time I make a chart. Is there a way to add + labs(caption ="Default") inside theme_bw()?

或者我可以同时使用 + labs(caption ="Default")和 + theme_bw()创建一个新对象，称为 + labs_and_theme

Or can I create a new object with both + labs(caption ="Default") and + theme_bw() that could be called as + labs_and_theme

ggplot(diamonds[1:20,], aes(x=carat, y=price)) + 
  geom_point() +
  labs(caption ="Default") +
  theme_bw()

推荐答案

您可以

library(ggplot2)
labs_and_theme <- list(
  labs(caption ="Default"),
  theme_bw() 
)
ggplot(diamonds[1:20,], aes(x=carat, y=price)) + 
  labs_and_theme + 
  geom_point()
