我是 R 新手，并试图在与 R 相同的页面上显示图形和图像。我尝试使用library(ggpubr)和ggarrange()运行。

导入我使用的图像library(png)并readPNG()导入我的图像。

我想要的最终结果是这样的：

在此处输入图像描述

我用来创建面板的代码是：

library(ggpubr)
library(png)

data("ToothGrowth")

bxp <- ggboxplot(ToothGrowth, x = "dose", y = "len",
                 color = "dose", palette = "jco")
dp <- ggdotplot(ToothGrowth, x = "dose", y = "len",
                color = "dose", palette = "jco", binwidth = 1)

img1 <- readPNG("image1.png")
img2 <- readPNG("image2.png")

im_A <- ggplot() + background_image(img1) # tried to insert the image as background.. there must be a better way
im_B <- ggplot() + background_image(img2) 

ggarrange(im_A, im_B, dp, bxp, 
          labels = c("A", "B", "C", "D"),
          ncol = 2, nrow = 2)

诅咒我使用power-point手动插入图像。

谢谢，

我认为您的代码几乎就在那里。如果您使用该theme函数添加一些边距，您可以获得如下内容：在此处输入图像描述

代码如下。唯一的补充是theme(plot.margin = margin(t=1, l=1, r=1, b=1, unit = "cm"))两个图像。

library(ggpubr)
library(png)

data("ToothGrowth")

bxp <- ggboxplot(ToothGrowth, x = "dose", y = "len",
                 color = "dose", palette = "jco")
dp <- ggdotplot(ToothGrowth, x = "dose", y = "len",
                color = "dose", palette = "jco", binwidth = 1)

img1 <- readPNG("~/Personal/Wallpapers/375501.png")
img2 <- readPNG("~/Personal/Wallpapers/665150.png")

im_A <- ggplot() + 
    background_image(img1) +
    # This ensures that the image leaves some space at the edges
    theme(plot.margin = margin(t=1, l=1, r=1, b=1, unit = "cm"))

im_B <- ggplot() + background_image(img2) + 
    theme(plot.margin = margin(t=1, l=1, r=1, b=1, unit = "cm"))

ggarrange(im_A, im_B, dp, bxp, 
          labels = c("A", "B", "C", "D"),
          ncol = 2, nrow = 2)
