我试图捕获某些R代码的输出并用乳胶代码替换它。

如果您运行此代码:

library(stargazer)
x <- capture.output(stargazer(mtcars[1:5, 1:3], summary = FALSE, title="The main caption of the table."))

x

这是输出:

 [1] ""

[19] "\\end{table} " 

我需要用这个代替第5行:

"  \\caption[short caption]{The main caption of the table.} "

我该怎么做?

尝试:

FILL_PARENT

这与您的想法略有不同,但也许您只能使用xtablecaption.width参数,例如:

print.xtable(xtable(mtcars[1:5, 1:3],
                    caption="The main caption of the table"),
             caption.width="10cm",
             caption.placement="top")

输出不会将完全移植到您要去的地方,但如果您更喜欢更简洁的代码,也许您可​​以根据自己的需要进行调整。来自?print.xtable

  

标题将放置在&#34; parbox&#34;如果caption.width不是NULL并且类型=&#34; latex&#34;,则指定宽度默认值为NULL。

这是输出:

% latex table generated in R 3.1.3 by xtable 1.7-4 package
% Tue Jun 30 14:52:06 2015
\begin{table}[ht]
\centering
\parbox{5cm}{\caption{The main caption of the table}} 
\begin{tabular}{rrrr}
  \hline
 & mpg & cyl & disp \\ 
  \hline
Mazda RX4 & 21.00 & 6.00 & 160.00 \\ 
  Mazda RX4 Wag & 21.00 & 6.00 & 160.00 \\ 
  Datsun 710 & 22.80 & 4.00 & 108.00 \\ 
  Hornet 4 Drive & 21.40 & 6.00 & 258.00 \\ 
  Hornet Sportabout & 18.70 & 8.00 & 360.00 \\ 
   \hline
\end{tabular}
\end{table}

您还必须使用其他选项(例如digits)来获取表格其余部分的确切格式以匹配来自stargazer的格式,具体取决于具体内容确切的格式就是你想到的。
