有谁知道是否可以在使用 grid.arrange() 创建的图表的每一列上给出标题？
我知道可以为每个图表提供总体标题和标题，但我只需要一个列标题。
非常感谢！
grid.arrange(c1b, c2a, c3d, c2b, c3a, c2d, c3b, c1a, c1d, ncol=3, nrow=3)

library(gridExtra)
#create a bunch of line graphs with the mtcars dataset
graph1 <- ggplot(mtcars, aes(x = mpg, y = disp)) + geom_line()
graph2 <- ggplot(mtcars, aes(x = mpg, y = hp)) + geom_line()
graph3 <- ggplot(mtcars, aes(x = mpg, y = drat)) + geom_line()
graph4 <- ggplot(mtcars, aes(x = mpg, y = wt)) + geom_line()
grid.arrange(arrangeGrob(graph1, graph2, top = "Column A"),
arrangeGrob(graph3, graph4, top = "Column B"), ncol = 2)
