COLOR(red){SIZE(30){Rのソースコードを[[LaTeX]]文書に記述する}}
Rのソースコードを[[LaTeX]]文書に記述するには、[[listings.sty:http://www.ring.gr.jp/pub/text/CTAN/macros/latex/contrib/listings/]]を使います。[[listings.sty:http://www.ring.gr.jp/pub/text/CTAN/macros/latex/contrib/listings/]]を使うと、Rソースファイルを構文強調して表示することができます。
R言語の定義は、lstlang3.sty に書かれています。

* [[listings.sty:http://www.ring.gr.jp/pub/text/CTAN/macros/latex/contrib/listings/]]の利用例
listings.styを使うと見出しをつけたり、任意の間隔で行番号をつけたり、さまざまな種類の枠をつけたり、プログラムコードのリスト（目次）を作成したり、いろいろなことができます。ここでは、単純に表示した例を示します。
** 利用例1
まずはデフォルトのままで表示する。
\documentclass{jsarticle}
\usepackage{listings}
\begin{document}
\begin{lstlisting}[language=R]
boa.acf <- function(link, lags)
# Brian Smith has produced the BOA (Bayesian Output Analysis) suite of
# S-plus/R functions for analysis of MCMC output, which reads in output
# from Classic BUGS or WinBUGS. Version 0.5.0 is now available.
{
pnames <- boa.pnames(link)
result <- matrix(NA, nrow = ncol(link), ncol = length(lags),
dimnames = list(pnames, paste("Lag", lags)))
lags <- lags[lags <= (nrow(link) - 1)]
n.lags <- length(lags)
if(n.lags > 0) {
idx <- 1:n.lags
lag.max <- max(lags)
for(i in pnames) {
result[i, idx] <- acf(link[, i], lag.max = lag.max,
plot = FALSE)$acf[lags + 1]
}
}
return(result)
}
\end{lstlisting}
\end{document}
出力結果
&ref(listings01.png,center);
** 利用例2
タイプライタ体にしてみる。デフォルトでは行間が空きすぎなので半分に狭くする。
\documentclass{jsarticle}
\usepackage{listings}
\lstset{%
language=R,
basicstyle={\ttfamily},
breaklines=true,
columns=[l]{fullflexible},
lineskip=-0.5zw,
}
\begin{document}
\begin{lstlisting}
boa.acf <- function(link, lags)
# Brian Smith has produced the BOA (Bayesian Output Analysis) suite of
# S-plus/R functions for analysis of MCMC output, which reads in output
# from Classic BUGS or WinBUGS. Version 0.5.0 is now available.
{
pnames <- boa.pnames(link)
result <- matrix(NA, nrow = ncol(link), ncol = length(lags),
dimnames = list(pnames, paste("Lag", lags)))
lags <- lags[lags <= (nrow(link) - 1)]
n.lags <- length(lags)
if(n.lags > 0) {
idx <- 1:n.lags
lag.max <- max(lags)
for(i in pnames) {
result[i, idx] <- acf(link[, i], lag.max = lag.max,
plot = FALSE)$acf[lags + 1]
}
}
return(result)
}
\end{lstlisting}
\end{document}

** 利用例3
カラー表示にしてみる。LaTeXでプレゼンテーションスライドを作成するときには、是非ともカラー表示にしたい。
\documentclass{jsarticle}
\usepackage[dvips]{color}
\usepackage{listings}
\definecolor{Brown}{cmyk}{0,0.81,1,0.60}
\definecolor{OliveGreen}{cmyk}{0.64,0,0.95,0.40}
\definecolor{CadetBlue}{cmyk}{0.62,0.57,0.23,0}
\lstset{%

stringstyle={\ttfamily},
commentstyle={\itshape\color{Brown}},
identifierstyle={\ttfamily\color{CadetBlue}\bfseries},
keywordstyle={\ttfamily\color{OliveGreen}},
basicstyle={\ttfamily},
breaklines=true,
columns=[l]{fullflexible},
lineskip=-0.5zw,
showstringspaces=ture
}
\begin{document}
\begin{lstlisting}
boa.acf <- function(link, lags)
# Brian Smith has produced the BOA (Bayesian Output Analysis) suite of
# S-plus/R functions for analysis of MCMC output, which reads in output
# from Classic BUGS or WinBUGS. Version 0.5.0 is now available.
{
pnames <- boa.pnames(link)
result <- matrix(NA, nrow = ncol(link), ncol = length(lags),
dimnames = list(pnames, paste("Lag", lags)))
lags <- lags[lags <= (nrow(link) - 1)]
n.lags <- length(lags)
if(n.lags > 0) {
idx <- 1:n.lags
lag.max <- max(lags)
for(i in pnames) {
result[i, idx] <- acf(link[, i], lag.max = lag.max,
plot = FALSE)$acf[lags + 1]
}
}
return(result)
}
\end{lstlisting}
\end{document}

さらにESS風(VineLinux標準のEmacsカラーテーマにess-modeを読み込んだ感じ)にしてみる。
\documentclass{jsarticle}
\usepackage{listings}

色強調するキーワードがess-modeと微妙に違うけれども、このあたりで妥協。
* lstlang3.styにおけるRの定義
Rのキーワードの定義は下記のようになっています。ここにリストされていない単語は、TeXソースの中で適宜追加すれば（つまり、language{R}を再定義する）キーワード扱いになります。
