从Rmarkdown产生PDF
我在Rstudio中使用rmarkdown尝试使用Rstudio提供的示例代码编写PDF（代码如下）：
---
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 {document}
pandoc.exe：从TeX源文件生成PDF错误错误：pandoc文件转换失败，错误43此外：警告消息：运行命令'“C：/ Program Files / RStudio / bin / pandoc / pandoc”+ RTS -K512m -RTS test_rmarkdown .utf8.md --to latex --from markdown + autolink_bare_uris + ascii_identifiers + tex_math_single_backslash-implicit_figures --output test_rmarkdown.pdf --template“C： Users XXXX Documents R win-library 3.2 rmarkdown rmd latex default.tex“ - 高亮样式探戈--latex-engine pdflatex - 变量”geometry：margin = 1in“'有状态43执行停止

我以前有类似的问题。 尝试运行devtools::install_github("rstudio/rmarkdown")这对我devtools::install_github("rstudio/rmarkdown") 。 如果你没有devtools，你需要运行它来：
install.packages("devtools")
library(devtools).
