R:xtable标题(或评论)

我想在xtable.打印的表格下面发表评论我认为最好的选择是使用“标题”选项:xtable(tablename, caption="This is a caption")。但这是以某种方式自动放入“表1”,因此输出看起来像:

  

表1:这是一个标题。

有没有办法抑制这种或任何更简单的方式将评论简单地作为表中的附加最后一行?

首先,一些模拟数据:

x <- sample(LETTERS, 5, replace = TRUE)
y <- sample(LETTERS, 5, replace = TRUE)
z <- table(x, y)

现在,使用print.xtable add.to.row参数,这是一个有点笨拙的解决方案。

comment          <- list()
comment$pos      <- list()
comment$pos[[1]] <- c(nrow(z))
comment$command  <- c(paste("\\hline \n",  # we`ll replace all default hlines with this and the ones below
                            "your footnote, caption or whatever.  \n",
                            sep = ""))
print(xtable(z),
      add.to.row = comment,
      hline.after = c(-1, 0))  # indicates rows that will contain hlines (the last one was defined up there)

如果您希望将评论放在数据之前,请使用comment$pos[[1]] <- c(0)代替comment$pos[[1]] <- c(nrow(z))并相应地调整hline.after

这是我的输出:

% latex table generated in R 2.14.1 by xtable 1.7-0 package

A &   0 &   0 &   0 &   1 \\ 
D &   1 &   0 &   0 &   0 \\ 
I &   0 &   0 &   0 &   1 \\ 
P &   0 &   0 &   1 &   0 \\ 
Z &   0 &   1 &   0 &   0 \\ 
\hline
your footnote, caption or whatever.  
\end{tabular}
\end{center}
\end{table}

这基本上是重新调整this答案,但这是使用xtable执行此操作的最具编程性的方法。它很难看,主要是因为我讨厌xtable add.to.row论证的工作方式。

示例数据:

set.seed(230)
DF <- data.frame(a = rnorm(5), b = rnorm(5), c = rnorm(5))

#of course, we can pass this directly below; I'm just saving
#  horizontal space for this answer
comm <- paste0("\\hline \n \\multicolumn{4}{l}",
           "{\\scriptsize{Check out these random numbers!}} \n")

print.xtable(xtable(DF, caption = "Describe the table"),
             #adjusting hline.after so that our comment appears
             #  "outside" the table, as defined by its border
             hline.after=c(-1, 0),
             #**NOTE: the first argument to add.to.row must be
             #  a list -- don't ask me why since it strikes me as odd**
             add.to.row = list(pos = list(5),
                               command = comm))

这里是TeX输出:

% latex table generated in R 3.2.4 by xtable 1.8-2 package
% Mon May 23 18:25:14 2016
\begin{table}[ht]
\centering
\begin{tabular}{rrrr}
  \hline
 & a & b & c \\ 
  \hline
1 & -0.23 & 0.04 & 1.34 \\ 
  2 & 0.10 & 0.57 & -1.62 \\ 
  3 & 0.33 & -0.14 & 0.83 \\ 
  4 & 0.36 & -0.75 & 0.20 \\ 
  5 & 0.44 & 0.13 & -0.49 \\ 
   \hline 
 \multicolumn{4}{l}{\scriptsize{Check out these random numbers!}} 
\end{tabular}
\caption{Describe the table} 
\end{table}

如果我用\documentclass{article}\begin{document}\end{document}包装它,那么.pdf结果:

当然,还有更多的花里胡哨可以添加它以使其准备好发布,但这是关键,你应该顺利完成。

如果您使用的是RMarkdown,请将其添加到标题中:

<cfoutput query="data">
    <script type="text/javascript">
       $.ajax({
          url: '/test.cfc',

          data:{
            q: #SerializeJSON(data)#, //is this how i pass it?
            method: "getData"
          },
          success: function(data) {
           console.log(data);
          }
      });
   </script>
</cfoutput>

在与xtable软件包维护者David(非常容易访问)交谈之后,他带来了我在下面发布的解决方案:

  

我认为这可以通过xtableList解决。创建一些数据并将数据框转换为xtableList。

---
(other configs here, like title, author, etc.)

header-includes:
    - \usepackage{caption}
    - \captionsetup{labelformat=empty}
---
  

然后xtable产生以下内容:

set.seed(230)
DF <- data.frame(a = rnorm(5), b = rnorm(5), c = rnorm(5))
library(xtable)
dfList <- list(DF)
attr(dfList, "message") <- c("A caption", "Which can have multiple lines")
  

要处理长字幕,您需要拆分行:

print(xtableList(dfList))
## % latex table generated in R 3.2.5 by xtable 1.8-3 package
## % Sat Jul 09 21:52:53 2016
## \begin{table}[ht]

## \begin{tabular}{rrrr}
## \hline
## & a & b & c \\
## \hline
## 1 & -0.23 & 0.04 & 1.34 \\
## 2 & 0.10 & 0.57 & -1.62 \\
## 3 & 0.33 & -0.14 & 0.83 \\
## 4 & 0.36 & -0.75 & 0.20 \\
## 5 & 0.44 & 0.13 & -0.49 \\
## \hline
## \multicolumn{4}{l}{A caption}\\
##
## \multicolumn{4}{l}{Which can have multiple lines}\\
## \end{tabular}
## \end{table}
