I&#39;ve created a grid of scatter plots (with regression lines) with my data using ```ggplot2```. Is there a simple way to add the R Squared of each regression line from ```geom_smooth``` to each facet in my plot?

library(tidyverse)

data %>% {
ggplot(., aes(x = ZAR_USD, y = GDP)) +
geom_point(size = 2) +
geom_smooth(method="lm", se=TRUE) +
facet_wrap(~Key, scales = 'free')
}

你可以使用 `{ggpmisc}` 包中的 `stat_poly_eq()` 函数来实现这个功能：
```r
library(ggpmisc)
library(tidyverse)
data %>%
ggplot(aes(x = ZAR_USD, y = GDP)) +
geom_point(size = 2) +
geom_smooth(method="lm", se=TRUE) +
stat_poly_eq(mapping = use_label("R2")) +
facet_wrap(~Key, scales = 'free')

这将得到以下结果：

英文:

You can do this using stat_poly_eq() from the {ggpmisc} package:

library(ggpmisc)
library(tidyverse)
data %&gt;% 
  ggplot(aes(x = ZAR_USD, y = GDP)) +
    geom_point(size = 2) +
    geom_smooth(method=&quot;lm&quot;, se=TRUE) +
    stat_poly_eq(mapping = use_label(&quot;R2&quot;)) +
    facet_wrap(~Key, scales = &#39;free&#39;)

which gives:
