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

Question

我收到错误，将Rmd文档编织为pdf。以下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时会抛出以下错误。

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，我发现错误的来源是我的代码中的退格\b和换行\n字符。但我无法找到解决这个问题的方法。

使用r代码块中的tidy =F选项似乎已经为我删除了错误。
