Rmarkdown: pandoc document conversion failed with error 43 because of large number

I ran into problems while knit the pdf in Rstudio via Rmarkdown. I suppose it stems from too many digits for the value of quoted r variable outside the chunk of code.

---
title: "R Notebook"
output:
pdf_document: default
html_notebook: default
---


```{r}
x <- 11111111111111
```

Testing for `r x`.

Error is 

! Missing $ inserted.
<inserted text> 
            $
l.133 Testing for 1.1111111\times

pandoc: Error producing PDF
Error: pandoc document conversion failed with error 43
Execution halted

Hope someone can help me out here.

This happens because long numbers are transformed to scientific notation (like 1.1e11) when printed, and because this scientific notation makes use of latex math symbol \times. There are two workarounds:

  1. Disable scientific notation. This can be done with options(). Add this chunk at the beginning of the document:

    ```{r, echo=FALSE}
options(scipen = 99)
```

  2. Print your number in a math environment with $ (this will preserve scientific notation):

    Testing for $`r x`$.
