转换*。*md。使用pdfRStudio-Convert*.mdto*.pdfusingRStudio

I think I have a MikTeX problem. In RStudio I clicked on the Knit PDF button and received this error message.

我想我有一个MikTeX问题。在RStudio中，我点击了编织的PDF按钮，并收到了这个错误消息。

This is pdfTeX, Version 3.1415926-2.3-1.40.12 (MiKTeX 2.9 64-bit)
pdflatex: The memory dump file could not be found.
pdflatex: Data: pdflatex.fmt

这是pdfTeX，版本3.1415926-2.3-1.40.12 (MiKTeX 2.9 64位)pdflatex:无法找到内存转储文件。pdflatex:数据:pdflatex.fmt

I then followed the first instruction at http://docs.miktex.org/manual/formats.html Then I rebooted my computer.

然后，我遵循了http://docs.miktex.org/manual/formats.html的第一个指令，然后重新启动了我的计算机。

At this point I do not know if I need to add a memory dump file and if so, the details of how to do so.

在这一点上，我不知道是否需要添加内存转储文件，如果需要，则需要添加该文件的详细信息。

I then tried Knit Word and that worked beautifully, producing a Word 2007 document.

然后我试着编织单词，效果很好，生成了一个Word 2007文档。

The real Rmarkup file is: IraAppliedStats.Rmd

真正的Rmarkup文件是:IraAppliedStats.Rmd。

Clicking on Knit produces the desired HTML file.

单击编织会生成所需的HTML文件。

I successfully ran the commands:

我成功地运行了命令:

install.packages("devtools"); devtools::install_github("rstudio/rmarkdown")

library(rmarkdown)

From the console I ran the following command, but I received an error.

从控制台我运行了下面的命令，但是我收到了一个错误。

render(input = "toPDF2.rmd", output_format = "pdf_document", output_file = "toPDF2.pdf")

I observed the monitor. After a few chunks were produced I started to see multiple messages such as the following after a few chunks were completed.

我观察到监视器。在完成几块后，我开始看到多个消息，比如在几个块完成后的后续消息。

*Warning in (if (out_format(c("latex", "sweave", "listings", "markdown"))) sanitize_fn else str_c)(path, : dots in figure paths replaced with _ ("IraAppliedStats_Rmd_files/figure-latex/unnamed-chunk-10")*

*警告(如果(out_format(c)(“latex”、“sweave”、“清单”、“markdown”)))(path，:图路径中的圆点替换为_(“IraAppliedStats_Rmd_files/图-latex/unnamed-chunk-10”)*。

Also each chunk had the following message.

每个块也有以下消息。

ordinary text without R code

普通文本没有R代码。

Much of the document is R code. The same line appears when I am producing the HTML file.

大部分文档都是R代码。当我生成HTML文件时，会出现相同的行。

The essence of the error message seems to be.

错误信息的本质似乎是这样的。

pandoc.exe: Error producing PDF from TeX source. This is pdfTeX, Version 3.1415926-2.3-1.40.12 (MiKTeX 2.9 64-bit) pdflatex: The memory dump file could not be found.

pandoc。exe:从TeX源生成PDF的错误。这是pdfTeX，版本3.1415926-2.3-1.40.12 (MiKTeX 2.9 64位)pdflatex:无法找到内存转储文件。

Using Notepad, I then added the following two lines to the top of the IraAppliedStats.md file.

然后，我使用记事本，将以下两行代码添加到伊拉克应用程序的顶部。md文件。

*title: IraAppliedStats.md output: pdf_document*

*标题:IraAppliedStats。md输出:pdf_document *

I closed Notepad.

我关闭记事本。

I again ran the command.

我再次运行命令。

render(input = "IraAppliedStats.Rmd", output_format = "pdf_document", output_file =    "IraAppliedStats.Rmd.pdf")

This did not appear to help as I again received an error message and there was no PDF file produced.

当我再次收到错误消息时，并没有生成PDF文件，这似乎没有帮助。

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. Click the **Help** toolbar button for more details on using R Markdown.

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.

library(rmarkdown)
render("Untitled.Rmd") # you could also use "Untitled.md"

  # Load packages.  
  require(knitr)
  require(markdown)

  # Process your .Rmd and generate a .pdf file 
  # (including smart punctuation and grey background of code blocks)
  # For this step you'll need to have two other programs installed on your computer
  # 1. Pandoc: http://johnmacfarlane.net/pandoc/installing.html
  # 2. LaTeX: follow the instructions on the Pandoc download page

  filen <- my_rmd_filename # name of the markdown file without .Rmd suffix
  knit(paste0(filen,".Rmd"))
  system(paste0("pandoc -s ", paste0(filen,".md"), " -t latex -o ", paste0(filen,".pdf"), " --highlight-))

  # Now find the location on your computer where the PDF file was created:
  getwd()
