R降价演示不显示情节

标签： r rstudio r-markdown

我在Windows上有Rstudio（下面是sessionInfo()），我正在尝试使用markdown构建一个r演示文稿。当我尝试编织HTML或PDF时，它似乎没有保留应该生成绘图的文件夹，因此我的演示文稿缺少绘图。我已经确认它确实可以使用基本的html_document。

有没有人对如何解决有任何想法？

## Area 1 ##
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)
```

## Area 2 ##
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.

这是使用knit html命令生成的，但是将html_document更改为ioslides_presentation并且它不会拾取情节

我发现了与RStudio-0.98.983和R-3.1.1-win相同的问题。卸载并重新安装并没有为我解决问题。我尝试过使用RStudio-0.98.994并且它也没有用...

更新：报告了这一点（见下面评论中的链接），RStudio团队找到了解决方案。在Windows上使用Lua base64编码器似乎是一个问题，它在ioslides中使用。解决方案是安装包httpuv或catools。重新启动RStudio后，问题应该得到解决（至少这对我来说！）。

答案 1 :(得分：4)

我有一个类似的问题，图表没有显示。原来，问题是我使用的.Rpres文件的名称中有空格。一旦我用下划线替换空格，情节就会再次出现。

使用“Example_File_Name.Rpres”而非“示例文件名.Rpres”。

答案 2 :(得分：0)

这是一个本地化问题 - 在新计算机上安装没有此错误。这可能是由于以前版本的R挂了 - 建议采取完全卸载R和Rstudio的路线。

卸载R和Rstudio有效。

答案 3 :(得分：0)

我遇到了同样的问题，并且不同的解决方案为我工作。 -不要将rmarkdown保存为文档名称中的任何数字， -并且也不要将文档名称中的.html包含在要保存的markdown文件中

仅使用不带上述两个名称的名称应在您指定的文件夹中创建一个rmd文件和一个html文件。 rmd文件将不包含图解，但是html文件应在其显示中包括它们。
