在r的一页上显示ggplot的多个图 [英] show multiple plots from ggplot on one page in r

问题描述

我想在一个循环中制作多个ggplot并将它们显示在一个图上.

I want to make multiple ggplot in a loop and show them on one plot.

for ( i in 1:8) {
    g <- ggplot(data=mtcars, aes(x=hp, y=wt))+
        geom_point()
    print(g)
}

我想将以上图解安排在一页，4行和2列上.有谁知道这是怎么做到的吗?谢谢.

I want to arrange the plots above on one page, 4 rows and 2 columns. Does anyone know how to do that? Thanks.

推荐答案

您可以将所有图解保存在list中，然后使用cowplot::plot_grid()或gridExtra::marrangeGrob()将它们放在一页或多页中

You can save all the plot in a list then use either cowplot::plot_grid() or gridExtra::marrangeGrob() to put them in one or more pages

另请参阅:

• 在ggplot2中创建任意窗格(patchwork，multipanelfigure和egg软件包)

for循环中有多个图

library(tidyverse)

# create a list with a specific length 
plot_lst <- vector("list", length = 8)

for (i in 1:8) {
  g <- ggplot(data = mtcars, aes(x = hp, y = wt)) +
    geom_point()
  plot_lst[[i]] <- g
}

# Combine all plots
cowplot::plot_grid(plotlist = plot_lst, nrow = 4)

library(gridExtra)
ml1 <- marrangeGrob(plot_lst, nrow = 2, ncol = 2)
ml1
