在R Markdown PDF表中包含图像 [英] Including an image in R Markdown PDF table

问题描述

我正在R Markdown中工作，编织成PDF.

I am working in R Markdown, knitting to PDF.

我认为以下代码应创建具有本地图像的表，但是它不起作用.任何帮助将不胜感激！

I thought the following code should create a table with a local image, but it is not working. Any help would be greatly appreciated!

column1 <- c("1", "2", "3")
column2 <- c("a", "b", "c")
column3 <- c("x", "y", "z")

dat <- data.frame(column1, column2, column3)

dat$column1[1] <- "![image1](green.png){ width=25px }"

print(kable(dat))

推荐答案

---
title: "pic in column"
author: "test"
date: "2014/08/03"
output: html_document

```{r results='asis'}
library(knitr)
column1 <- c("1", "2", "3")
column2 <- c("a", "b", "c")
column3 <- c("x", "y", "z")

dat <- data.frame(column1, column2, column3)

dat$column1<- sprintf('![](green.png)')

print(kable(dat))
```

我只是使用了注释中的链接，并将您的问题放入代码中.如果您想为每行使用不同的图片，则可能需要将文件名保存为向量.在该示例中，您还可以使用网页中的图像

I just used the link in the comments and fit your question into the code. if you wanted different pictures for each row, you maybe need to save the file names into a vector. In the example you could also use images from a webpage
