循环中的knitr模板和子文档 [英] knitr templates and child documents in a loop

问题描述

在圣诞节之前，我之前曾问过跨多个编织文档的单个样式表.我现在知道我缺少的关键搜索词是子文档".

Before Christmas I previously asked single style sheet across multiple knitr documents. I now know that the key search term I was missing is "child document".

我创建了一个最小的markdown示例，但是我在创建的文档中得到了标题，这些标题是编织过程的一部分.我正在使用RStudio对其进行处理.我见过许多类似的问题，但是没有一个答案有效.到目前为止，我已经尝试了块参数的各种组合，但无济于事.

I have created a minimal markdown example but I am getting headers in the created document that are part of the knitting process. I am using RStudio to process it. I have seen many similar questions, but none of the answers work. I have tried various combinations of the chunk parameters and so far to no avail.

问题:如何摆脱最终编织文档的标题?

Question: How do I get rid of the header from the final knitted document?

# Master document

```{r master1, comment='', echo=FALSE, message=FALSE, warning=FALSE, results="asis", fig.width= 4., fig.height= 4, fig.cap= ""}
out = NULL
for (i in 1:3) {
  # lets create three different uniform data sets.
  v1 <- sort(rnorm(2))
  uvec <- runif(10, v1[[1]], v1[[2]])
  # now we want to 
  out <- c(out, knit_child('child.Rmd'))
}
cat(paste(out, collapse = '\n'))
```

子文档包含:

## child document `r i`

Here is a summary of the dataset:
```{r echo=FALSE}
summary(uvec)
```

不幸的是，我也得到了一个烦人的标题....

Unfortunately I also get an annoying header ....

推荐答案

一个答案是使用knit_expand()代替knit_child()并稍后使用knit(, quiet=TRUE)-这是经过修订的主文档.

One answer is to use knit_expand() instead of knit_child() and to knit(, quiet=TRUE) later - here is a revised master document.

# Master document
```{r master1, comment='', echo=FALSE, message=FALSE, warning=FALSE, results="asis", fig.width= 4., fig.height= 4, fig.cap= ""}
out = NULL
for (i in 1:3) {
  # lets create three different uniform data sets.
  v1 <- sort(rnorm(2))
  uvec <- runif(10, v1[[1]], v1[[2]])
  out <- c(out, knit_expand('child.Rmd'))
}
cat(knit(text=unlist(paste(out, collapse = '\n')), quiet=TRUE))
```
