向多个ggplot图添加自定义"+“

library(ggplot2)
library(ggpubr)

# 创建第一个ggplot图
plot1 <- ggplot(mtcars, aes(x = mpg, y = disp)) +
  geom_point() +
  labs(title = "Plot 1")

# 创建第二个ggplot图
plot2 <- ggplot(mtcars, aes(x = mpg, y = hp)) +
  geom_point() +
  labs(title = "Plot 2")

# 创建第三个ggplot图
plot3 <- ggplot(mtcars, aes(x = mpg, y = wt)) +
  geom_point() +
  labs(title = "Plot 3")

# 将三个图组合在一起
combined_plot <- ggarrange(plot1, plot2, plot3, nrow = 1, ncol = 3)

# 显示组合后的图
print(combined_plot)
