R: Knitr Syntax expression as text

Question

I'm using the knitr package with RStudio and want to write the following expression as text in my output pdf file:

\Sexpr{pi}

I tried the LaTeX math mode:

$\Sexpr{pi}$

but it will give me the value and not the text.

Answer 1

Write \textbackslash{}Sexpr\{pi\}.
