使用xtable和tabular.environment将inset\footnote {}放入标题中

Question

我可以控制的add.to.row命令xtable放置一个\footnote{}在LaTeX表输出头？

这是我走了多远.(我想找到一个使用xtable而不是'Hmisc' 的解决方案)

require(xtable)
x <- matrix(rnorm(60), ncol = 10)
x.big <- xtable(x,label='tabbig', caption='Example of longtable')
names(x.big) <- LETTERS[1:10]
print(x.big,tabular.environment='longtable',floating=FALSE, 
      add.to.row = list(pos = list(seq(1,nrow(x.big), by = 2), 0, 1),
      command = c("\\rowcolor[gray]{.95} ", "\\hline \\endhead ", 
      "\\footnote{This is the first footnote that I would like to have 
      in the headder next to `I'.}") ) )

然后我在小乳胶文件中使用输出.像这样:

\documentclass{article}
\usepackage{longtable} 
\usepackage{colortbl} 
\usepackage[landscape]{geometry}

\begin{document}
I
\vspace{100 mm}

   \rowcolor[gray]{.95}  \footnote{This is the first footnote that I would like to have in the headder next to `I'.}2 & -0.45 & -0.06 & 0.13 & 0.20 & 0.26 & 0.48 & 0.07 & 0.45 & -0.51 & 1.26 \\

   \rowcolor[gray]{.95} 4 & -1.60 & -0.69 & -0.11 & 2.12 & -0.12 & -1.81 & -1.51 & 0.67 & 0.22 & 0.43 \\ 
  5 & -0.26 & 0.14 & 0.86 & -0.78 & -2.04 & 1.17 & -1.48 & -0.38 & 0.80 & 1.49 \\ 
   \rowcolor[gray]{.95} 6 & -0.53 & -0.43 & -0.84 & 0.06 & -0.87 & 1.13 & -0.56 & 0.30 & -0.96 & 1.75 \\ 
   \hline
\hline
\caption{'Example of longtable'}
\label{tabbig}
\end{longtable}

\end{document}

这会产生这个表,

我认为你不能使用add.to.row参数来操纵头部 .

但为什么不进行消毒呢？

在这里我的解决方案:想法是在标题中添加一个标记(这里是脚注)并使用sanitize选项更改它.

x <- matrix(rnorm(60), ncol = 10)
x.big <- xtable(x,label='tabbig', caption='Example of longtable')
names(x.big) <- LETTERS[1:10]
names(x.big)[9] <- paste('I','footnote')    # I put the tag on I letter 
print(x.big,tabular.environment='longtable',floating=FALSE,
      sanitize.text.function=function(str)gsub("footnote","\\footnote{my tricky footnote !!}",str,fixed=TRUE))

您可以使用许多标签轻松地将解决方案扩展到许多脚注.

更新,多个脚注的案例

您可以轻松地使用这些技巧来处理多个音符,如下所示:

names(x.big)[1] <- paste('A','footnote1')    # I put the tag on A letter 
names(x.big)[9] <- paste('I','footnote2')    # I put the tag on I letter 
print(x.big,floating=FALSE,
      sanitize.text.function=function(str){
        str <- gsub("footnote1","\\footnote{my tricky footnote 1 !!}",str,fixed=TRUE)
        str <- gsub("footnote2","\\footnote{my tricky footnote 2 !!}",str,fixed=TRUE)
      }
        )

这个想法是在正则表达式替换后分配相同的字符串.
