使用knitr和LateX，如何避免上面的.png路径;以及如何在桌子中并排放置两个地块

Question

LateX的新手，我有两个问题或者knitr。运行跟随PDF生成的图像的代码，继续出现.png图上方路径的三次重复。

其次，并排表中的.png图像根本没有出现。

我希望得到纠正和教育。

\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>>=

% \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}

Answer 1

文件名中包含空格，您需要添加

\usepackage{grffile}

到你的序言。此外，一旦在\graphicspath{..}中指定了适当的集合，就可以删除\includegraphics命令中的所有此类路径引用。
