Knitr 'asis' option not working when R produces LaTeX code

Question

I am running a process where I automatically produce a report. It has worked up until a point. But now knitr::opts_chunk$set(result='asis') does not work when I cat LaTeX code into the document. It replaces the \\ with \\textbackslash{} when I knit the document. Even though if you run the cat command on its own, it produces the correct LaTeX code:

---
title: "Untitled"
date: "October 15, 2017"
output: pdf_document
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE, comment = NA, background = NA, results='asis')
```

```{r}
cat("
  \\begin{tabular*}{1\\textwidth}{c c}
  \\parbox[c]{0.4\\linewidth}{
    {\\HUGE{\\textcolor{blue}{\\textbf{\\uppercase{Headline}}} }}\\\\
    \\Large{{\\textsc{Example}}}\\\\
  }&
    \\parbox{0.25\\textwidth}{
      \\icontext{MapMarker}{12}{Global}\\\\
      \\icontext{MobilePhone}{12}{999 666 23}\\\\
      \\icontext{Send}{12}{someemail@gmail.com}\\\\
    }
  \\end{tabular*}")
```

The error being produced:

I have tried using knitr::asis_output() , but it results in the same error

The Tex being produced is the following:

\begin{document}
\maketitle

\textbackslash{}begin\{tabular\emph{\}\{1\textwidth\}\{c c\}
\parbox[c]{0.4\linewidth}{
    {\HUGE{\textcolor{blue}{\textbf{\uppercase{Headline}}} }}\\
    \Large{{\textsc{Example}}}\\
  }\& \parbox{0.25\textwidth}{
      \icontext{MapMarker}{12}{Glogab}\\
      \icontext{MobilePhone}{12}{999 666 23}\\
      \icontext{Send}{12}{someemail@gmail.com}\\
    } \textbackslash{}end\{tabular}\}

\end{document}

Answer 1

There is finally a solution to these issues:

knitr::raw_latex("here all your tex content") 

instead of cat() + results='asis'.
