编织器:将代码块中的文本打印为R降价 [英] Knitr: print text from code block as R markdown

问题描述

我有以下R Markdown文件:

I have the following R Markdown document:

---
title: "Test"
output: html_document
---

```{r cars, echo=FALSE}
myCondition <- TRUE
if(myCondition) {
  print("## Car Summary")
}
summary(cars)
```

当我将其编织为HTML时，汽车摘要"标头以类似终端的"等宽字体呈现，如下所示:

When I Knit it to HTML, the "Car Summary" header is rendered in "terminal-like" monospaced font as this:

## [1] "## Car Summary"

但是我希望它呈现为标题.我该如何实现?

But I want it rendered as a header. How do I achieve this?

推荐答案

这应该对您有用:

```{r cars, echo=FALSE, results='asis'}
myCondition <- TRUE
if(myCondition) {
  cat("## Car Summary")
}
```

```{r, echo=FALSE}
summary(cars)
```

请注意，选项results = 'asis'对于打印页眉很重要.另请注意，print()将不起作用，但是cat().

Note that the option results = 'asis' is important to print the header. Also note that print() will not work, but cat().
