使用knitr和LateX，如何避免.png以上的路径； 以及如何在表格中并排放置两个地块

Question

New to LateX, I have two problems with it or knitr. Running the code that follows the image of what is produced in PDF, there continue to appear three repetitions of the the path above the .png figure.

Second, the side-by-side table with a .png image in each is not appearing at all.

I would appreciate being corrected and educated.

\documentclass[11pt]{article}  

\usepackage{fullpage}
\usepackage[margin=1in]{geometry}

\usepackage{color}

% \usepackage{framed}

\usepackage{graphicx}  % to import .png files
\usepackage{tabularx}  % note that there is no tabular package
\usepackage{fancyhdr}

\lhead{Survey Graphics}
\rhead{Pg. \thepage}
\cfoot{$\copyright$ lawyeR}

<<echo=FALSE, results="hide", warning=FALSE, message=FALSE>>=
lm_blue <- "#003767"
@

% \renewcommand
% \headrule{ 
% \color{lm_blue}
% \begin{minipage}{1\textwidth}
% \hrule width \hsize height 5pt 
% \end{minipage}}%
% 
% \newcommand{\HRule}[1]{\hfill \rule{0.2\linewidth}{#1}} % Horiz rule at bottom of page, adjust width here
% 
% \renewcommand{\headrulewidth}{0.4pt}
% \renewcommand{\footrulewidth}{0.1pt}  
% \addtolength{\headheight}{0.5pt}  

%% end preamble; begin document


\begin{document}

\graphicspath{ {C:/Users/blank/Documents/Marketing and Blog/ReproData Book Survey/Plots and images/} }

\begin{figure}[h]    
\begin{center}

Answer 1

With spaces in your filenames, you need to add

\usepackage{grffile}

to your preamble. Additionally, once you've specified an appropriate set in \\graphicspath{..} , you can remove all such path references in the \\includegraphics commands.
