有没有办法包含来自其他目录的子Rmd文件 [英] Is there a way to include child Rmd files from a different directory

问题描述

我有一个主要的降价文件，例如Parent.Rmd，以及随附的许多子文档:

I have a master markdown file, e.g., Parent.Rmd, and a number of child documents being included with:

```{r child="introduction.Rmd", echo=FALSE}
```

```{r child="chapter2.Rmd", echo=FALSE}
```

看来我应该能够做到:

```{r child="Rmd/introduction.Rmd", echo=FALSE}
```

从名为"Rmd"的子目录中提取相同的文件，但knitr无法打开连接.

to pull the same file from a sub directory named 'Rmd' but knitr can't open the connection.

我也尝试使用:

`knitr::opts_chunk$set(child.path='Rmd')`

，但块代码将忽略它.还有另一种方法吗?我的rmarkdown版本是0.9.5，knitr是1.12

but the chunk code ignores it. Is there another way? My rmarkdown version is 0.9.5 and knitr is 1.12

希望，@Yihui可以比我在这里提出的解决方案更优雅地回答您的问题. :)

hopefully, @Yihui will be able to answer your question more elegantly than my proposed solution here. :)

我早些时候在这里进行过黑客攻击在R中包含HTML文件降价文件?.而且该方法也可以满足您的要求

i did a hack earlier here Include HTML files in R Markdown file?. And the method should work for your requirements as well

bookstruct.Rmd文件:

bookstruct.Rmd file:

---
title: "BookTitle"
output: html_document
---

My introduction goes here

<<insertHTML:[chapters/chapter2.Rmd]

some practice questions

<<insertHTML:[chapters/chapter3.Rmd]

chapters/chapter2.Rmd文件:

chapters/chapter2.Rmd file:

## Chapter 2

This is my chapter 2.

chapters/chapter3.Rmd文件:

chapters/chapter3.Rmd file:

## Chapter 3

This is my chapter 3.

在R控制台中，运行以下命令:

In R console, run this:

library(stringi)

subRender <- function(mdfile, flist) {
    #replace <<insertHTML:flist with actual html code
    #but without beginning white space
    rmdlines <- readLines(mdfile)
    toSubcode <- paste0("<<insertHTML:[",flist,"]")
    locations <- sapply(toSubcode, function(xs) which(stri_detect_fixed(rmdlines, xs)))
    subfiles <- lapply(flist, function(f) stri_trim(readLines(f)))
    strlens <- sapply(subfiles,length)

    #render html doc
    newRmdfile <- tempfile("temp", getwd(), ".Rmd")

    #insert flist at specified locations
    #idea from @Marek in [2]
    alllines <- c(rmdlines[-locations], unlist(subfiles))
    ind <- c( (1:length(rmdlines))[-locations],
        unlist(lapply(1:length(locations), function(n) locations[n] + seq(0, 1, len=strlens[n])/1.1 )) )
    sortedlines <- alllines[order(ind)]

    #render html
    write(sortedlines, newRmdfile)
    rmarkdown::render(newRmdfile, "html_document")
    shell(gsub(".Rmd",".html",basename(newRmdfile),fixed=T))
} #end subRender

subRender(mdfile="bookstruct.Rmd",
    flist=list("chapters/chapter2.Rmd", "chapters/chapter3.Rmd"))
