Rstudio转换为PDF [英] Rstudio knit to PDF

问题描述

Rstudio(0.98.932)的新版本具有许多新选项，包括编织到PDF".描述新版本的文章有戴夫(Dave)的评论，内容为:

The new version of Rstudio (0.98.932) has many new options including knit to PDF. An article describing the new version has a comment from Dave that says:

...在安装rstudio 0.98.932之后，我没有看到下拉菜单 编辑.Rmd文件时用于编织pdf或word.

...after installing rstudio 0.98.932 I don’t get the little dropdown menu for knit-pdf or word when editing a .Rmd file.

我遇到了同样的问题.发布了一个有用的回复:

I'm having the same issue. A helpful response was posted:

可能是:

a)您没有运行R 3.0(RMarkdown v2必需)；或

a) You are not running R 3.0 (which is required for RMarkdown v2); or

b)您定义了一个自定义的markdown渲染器(markdownToHTML 选项).您可以通过执行以下操作进行检查:

b) You have a custom markdown renderer defined (markdownToHTML option). You can check for this by executing:

getOption("rstudio.markdownToHTML")

getOption("rstudio.markdownToHTML")

这解决了Dave的问题(b)，但是当我运行该命令时，我得到了NULL

That solved Dave's problem (b), but when I run that command I get NULL

> getOption("rstudio.markdownToHTML")
NULL

我认为这意味着我没有定义自定义markdown渲染器. (以前我是在自定义的.Rprofile中进行的，但是我删除了它.)我的R版本是3.1.0.

Which I assume means I don't have a custom markdown renderer defined. (Previously I did in a cusomized .Rprofile, but I removed that.) My R version is 3.1.0.

我误解了getOption命令吗?可能是我的Rstudio绊倒了吗?

Am I misunderstanding the getOption command? Could something else be tripping up my Rstudio?

推荐答案

我刚刚安装了RStudio的新版本(0.98.932)，这促使我升级了几个软件包(尽管我记不清哪个，我看到我有knitr 1.6，markdown 0.7和rmarkdown 0.2.46).起初我有同样的问题.工具栏上只有一个编织"选项.通过在我的.Rmd文件的开头添加以下内容，我设法能够编织成.pdf.

I have just installed the new version of RStudio (0.98.932), which prompted me to upgrade a couple of packages (I can't remember which, although I see I have knitr 1.6, markdown 0.7 and rmarkdown 0.2.46). At first I had the same problem; there was only a single 'knit' option on the tool bar. I managed to get the ability to knit to .pdf by adding the following to the head of my .Rmd file.

---
title: "Sample Document"
output: pdf_document
---

这样做之后，我现在发现我确实有一个下拉菜单，其中包含用于编织为HTML，PDF和word的选项.还有一个小齿轮图标，可用来访问以前没有的R Markdown文档选项.我不知道问题出在哪里，但现在看来还可以！

Having done that, I now find I do have a drop down menu with options to knit to HTML, PDF and word. There's also a little gear icon that provides access to the R Markdown document options that wasn't there before. I have no idea what the problem was but it seems OK now!
