从 Rmarkdown 生成 PDF

Question

我在 Rstudio 中使用 rmarkdown 尝试使用 Rstudio 提供的示例代码（代码如下）来编织 PDF：

---
title: "Untitled"
output: 
  pdf_document: 
    keep_tex: yes
---

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.

When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

```{r}
summary(cars)
```

You can also embed plots, for example:

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

Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.

但是，我收到以下错误：

！ pdfTeX 错误（字体扩展）：自动扩展仅适用于可缩放 字体。 \AtBegShi@Output ...ipout \box \AtBeginShipoutBox \fi \fi l.144 \end{文档}

我以前也遇到过类似的问题。 尝试运行devtools::install_github("rstudio/rmarkdown") 这对我有用。 如果你没有 devtools，你需要运行它：

install.packages("devtools")
library(devtools).
