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

Question

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.

Answer 1

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 $`r x`$.
