[Tex/LaTex] Latex code in knitr script

Question

I'm using knitr to rewrite some documents originally written in latex.
Here is the preamble of the knitr

---
title: "Blabla"
date: "May 2, 2017"
bibliography: allpapers.bib
output:
  word_document:
    fig_caption: true
    reference_docx: "Empty.docx"
---

Now, in the original latex version I was using this:

\newcommand{\myinput}[1]{%
  \begingroup%
  \renewcommand\normalsize{\small}% Specify your font modification
  \input{#1}%
  \endgroup%
}
\begin{centering}
\myinput{table1.txt}
\end{centering}

The table1.txt is a prefomated latex table. I would like to include
these tables in the “knitrdocument without rewriting them from scratch, by just includingtable1.txtin theknitr`, somehow. How can this be done?

PS the table1.txt files have the form:

\begin{table}[ht]
\centering
\begin{tabular}{rllr}
  \hline
 & sdsd & dfdf & sdsd \\ 
  \hline
1 & sdsd & sdsd & -1.04 \\ 

   \hline
\end{tabular}
\caption{blabl.} 
\label{table1}
\end{table}

Answer 1

You can include LaTeX code verbatim in RMarkdown source files, and when you output to a format that uses LaTeX (i.e., pdf), the LaTeX is treated exactly as you expect.

However, if you're exporting to a non-LaTeX format, such as a word doc or html, then the exporter will just ignore the LaTeX.

This is a test. Here's some \LaTeX{}:

\newcommand{\myinput}[1]{%
  \begingroup%
  \renewcommand\normalsize{\small}% Specify your font modification
  \input{#1}%
  \endgroup%
}
\begin{centering}
\myinput{table1.txt}
\end{centering}

Now I'm done.
