在Rstudio 0.98.994上编织到Pdf时出现Inputenc / Pandoc错误

Question

将Rmd文档编织为pdf时出现错误。 这是导致错误的代码部分。

```{r chunk5 ,echo=F}

hypoconf<-function(z){if(z=="dose"){

                 cat(paste(as.character(1),"\b. If there is no difference in 
                 tooth  growth  for" ,z,   "of",as.character(20),"and"     
                 as.character(10),"the probability of seeing the     
                 observed or more extreme outcome is", as.character(30),"percent."))  

                 cat("\n\n") 
            }
hypoconf("dose")  
```  

编织为pdf时会引发以下错误。

output file: report2.knit.md

pandoc: Error producing PDF from TeX source.
! Package inputenc Error: Keyboard character used is undefined
(inputenc)                in inputencoding `utf8'.

See the inputenc package documentation for explanation.
Type  H <return>  for immediate help.
...                                              

l.260 \end{verbatim}

Try running pandoc with --latex-engine=xelatex.
Error: pandoc document conversion failed with error 43
Execution halted

当我编织到html时，我没有得到相同的错误。 另外，我发现错误源是代码中的退格\\b和换行\\n字符。 但是我找不到解决这个问题的方法。

在r代码块中使用tidy =F选项似乎为我消除了错误。
