使用Pander + Knitr创建PDf文件的问题:将带有标题的表格放置在地图上并直接彼此相邻时出错 [英] Issue with creating PDf file with Pander+Knitr: Error when putting table with caption and plot directly next to each other

问题描述

我的pander(+ knitr)有一个可重现的错误: 将带有标题的表格和图表直接相互放置时，我无法创建PDF文件.我在Windows上使用pander 0.5.1，knitr 1.7，R版本3.1.1，Miktex + RStudio.

I have a reproducible error with pander (+ knitr): When a table with caption and a plot is put directly to each other, I cannot create a PDF File. I use pander 0.5.1, knitr 1.7, R version 3.1.1, Miktex + RStudio on Windows.

因此，以下内容将产生错误(另请参见下面的我的错误和非错误列表"):

So the following will produce the error (see also my List of errors and non-errors below):

```{r, echo=FALSE, eval=TRUE}
pander(cor(cars), caption="Whatever" ) # or some other captioned table

hist(cars$speed) #or some other plot

```

pandoc.exe: Error producing PDF from TeX source Fehler: pandoc document conversion failed with error 43 Zus�tzlich: Warnmeldung: Ausf�hrung von Kommando '"C:/Program Files/RStudio/bin/pandoc/pandoc" Teste_markdown_Cor+Hist.utf8.md --to latex --from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash-implicit_figures

当我手动复制并粘贴pander的输出时，问题似乎出在情节之前是空行:

When I manually copy&paste the output from pander, the issue seems to be with an empty line before the plot:

不工作:

--------------------------
        speed   dist 
----------- ------- ------
 **speed**     1    0.8069

 **dist**   0.8069    1   
--------------------------

Table: K
```{r, echo=FALSE, eval=FALSE}
hist(cars$speed)
```

工作无误

--------------------------
        speed   dist 
----------- ------- ------
 **speed**     1    0.8069  
 **dist**   0.8069    1   
--------------------------

Table: K

```{r, echo=FALSE, eval=FALSE}
hist(cars$speed)
```

但是，即使我在平移器和绘图之间的代码块中放置了不同的空行，错误仍然存​​在

But even if I put different empty lines in the code-chunk between pander and the plot, the error continues

# Does not work

```{r, echo=FALSE}
library(pander)
```

Does not work:
```{r, echo=FALSE, eval=TRUE}
pander(cor(cars), caption="Korrelationen" )
hist(cars$speed)

```

Does not work :
```{r, echo=FALSE, eval=FALSE}
pander(cor(cars), caption="Korrelationen" )
plot(cars)

```

Does not work:
```{r, echo=FALSE, eval=FALSE}
pander(cor(cars), caption="K" )
plot(cars)
```

Does not work:
```{r, echo=FALSE, result='asis', comment=NA,  eval=FALSE}
    pander(cor(cars), caption="Korrelationen" )

 #several line breaks


hist(cars$speed)

```    

Doesnt Work: 

--------------------------
        speed   dist 
----------- ------- ------
 **speed**     1    0.8069

 **dist**   0.8069    1

# Works without Error

Works:
```{r, echo=FALSE, eval=TRUE}
cat("Korrelationen")
hist(cars$speed)

```

Works:
```{r, echo=FALSE, eval=TRUE}
pander(cor(cars), caption="Korrelationen" )
cat("Korrelationen")
hist(cars$speed)

```

Works:
```{r, echo=FALSE, eval=TRUE}
cat("table: Korrelationen")
hist(cars$speed)

```

Works:
```{r, echo=FALSE, result='asis', comment=NA,  eval=TRUE}
pander(cor(cars), caption="Korrelationen" )
cat("table: Korrelationen")
hist(cars$speed)

```

推荐答案

我找到了一种解决方法，手动在字幕的末尾添加了换行符.但是我仍然认为应该将其视为错误?！?

Works:
```{r, echo=FALSE, eval=TRUE}
pander(cor(cars), caption="whatever text\n" )
hist(cars$speed)

```
