conditionalstwo-column
I am writing a paper in LaTeX. I will need both the one-column and two-column versions of the paper. For this, the figure sizes/configurations need to be different in the two documents. I am looking for a command like \iftwocolumn! Do you know if it exists and if not how can I define and use it?
I would need something like:
\begin{figure}[tb]
\iftwocolumn\includegraphics[width=0.7\linewidth]{FiguresDouble/figure.eps}
\else\includegraphics[width=0.5\linewidth]{FiguresSingle/figure.eps}
\fi
This is a way to span the tikzpicture across two column. adjustbox package is used where the width is set to \linewidth for the span. width=\columnwidth would back to regular result.
Code
\documentclass[twocolumn,11pt]{article}
\usepackage{tikz}
\usepackage{lipsum,adjustbox}
\usetikzlibrary{calc,positioning}
\begin{document}
\definecolor {processblue}{cmyk}{0.96,0,0,0}
\begin {figure*}%[!hbtp]
\centering
\begin{adjustbox}{width=\textwidth}
\begin {tikzpicture}[-latex ,auto,node distance =1.8cm and 1.5cm ,on grid,semithick,
state/.style ={ circle ,top color =white , bottom color = processblue!20,
draw,processblue , text=blue , minimum width =1 cm}]
\node[state] (S) {$S$};
\node[state] (W) [above right =of S] {$W$};
\node[state] (X) [right =of W] {$X$};
\node[state] (Y) [right =of X] {$Y$};
\node[state] (Z) [right =of Y] {$Z$};
\node[state] (D) [below right =of Z] {$D$};
\path (S) edge [bend left =0] node[above left = .3 cm] {$R_{sw}$} (W);
\path (W) edge [bend right =0](S);
\path (W) edge [bend left =0] node[above = .3 cm] {$R_{wx}$}(X);
\path (X) edge [bend right =0](W);
\path (X) edge [bend left =0] node[above = .3 cm] {$R_{xy}$}(Y);
\path (Y) edge [bend right =0](X);
\path (Y) edge [bend left =0] node[above = .3 cm] {$R_{yz}$}(Z);
\path (Z) edge [bend right =0](Y);
\path (Z) edge [bend left =0] node[above right = .3 cm] {$R_{zd}$}(D);
\path (D) edge [bend right =0](Z);
{\tiny }
\end{tikzpicture}
\end{adjustbox}
\end{figure*}
\lipsum[1-6]
\end{document}
After searching for a very long time, I found out a simple solution using multicols.
\usepackage{multicol}
\usepackage{graphicx}
\begin{document}
\begin{figure*}
\begin{multicols}{2}
\includegraphics[width=\linewidth]{figure name}\par
\includegraphics[width=\linewidth]{figure name}\par
\end{multicols}
\begin{multicols}{2}
\includegraphics[width=\linewidth]{figure name}\par
\includegraphics[width=\linewidth]{figure name}\par
\end{multicols}
\caption{caption here}
\end{figure*}
\end{document}
This makes it very easy to add figures in a two-column file.

\linewidthor\columnwidthshould work, since a non-twocolumndocument technically consists of a single column (of width\columnwidth).However, if you're using the traditional
twocolumnmode of (say)article, the condition\if@twocolumnis available for testing/branching.Here's a short example showing the difference:
Note that you require the use of a
\makeatletter...\makeatotherpair, since the command definition of the conditional contains@. See What do\makeatletterand\makeatotherdo?
