使用Pander + Knitr创建PDf文件时出现问题：将带有标题的表格和绘图直接放在彼此旁边时出错

Question

我有一个可重复的错误与pander（+ knitr）： 当带有标题和绘图的表直接相互放置时，我无法创建PDF文件。我在Windows上使用pander 0.5.1，knitr 1.7，R 3.1.1，Miktex + RStudio。

因此，以下内容将产生错误（另请参阅下面的错误和非错误列表）：

```{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，问题似乎是在情节之前用空行：

不起作用：

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

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

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

无错误地工作

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

Table: K

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

但即使我在pander和plot之间的代码块中放入了不同的空行，错误也会继续

# Does not work

```{r, echo=FALSE}

```

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

```

Does not work :
```{r, echo=FALSE, eval=FALSE}

plot(cars)

```

Does not work:
```{r, echo=FALSE, eval=FALSE}

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

# 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)

```

Answer 1

我找到了一种解决方法，在标题末尾手动添加换行符。但我仍然认为这应该被视为一个错误？！

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

```
