使用gsub修改xtable命令的输出

标签: r

my.mat< - cbind(1:5,rnorm(5),6:10,rnorm(5))     colnames(my.mat)< - c(“Turn”,“Draw”,“Turn”,“Draw”)     打印(xtable(my.mat))

产量

\begin{table}[ht]
\begin{center}
\begin{tabular}{rrrrr}
  \hline
 & Turn & Draw & Turn & Draw \\ 
  \hline
1 & 1.00 & -0.72 & 6.00 & 0.91 \\ 
  2 & 2.00 & 0.57 & 7.00 & 0.56 \\ 
  3 & 3.00 & 1.08 & 8.00 & 0.55 \\ 
  4 & 4.00 & 0.95 & 9.00 & 0.46 \\ 
  5 & 5.00 & 1.94 & 10.00 & 1.06 \\ 
   \hline
\end{tabular}
\end{center}
\end{table}

我想过滤掉\ begin {table}和\ end {table}行。我可以使用gsub做到这一点,但是如何获得print的结果(xtable(...变成一个变量?

感谢Stack Overflow R社区的帮助!

在我的.Rnw中,我有

\begin{tablehere}
{

<<echo=false,results=tex>>=
library(xtable)
my.mat <- cbind(1:5, rnorm(5), 6:10, rnorm(5))
colnames(my.mat) <- c("Turn", "Draw","Turn", "Draw")
#print(xtable(my.mat))

x <- capture.output(print(xtable(my.mat)))
x <- gsub("\\\\begin\\{tabular\\}.*", "", x, perl=TRUE)
x <- gsub("\\\\end\\{tabular\\}.*", "", x, perl=TRUE)
print(x)

@ 

 }
\end{tablehere}

导致

\begin{tablehere}
{

 [1] "% latex table generated in R 2.9.2 by xtable 1.5-5 package"
 [2] "% Mon May 17 20:23:09 2010"                                
 [3] "\\begin{table}[ht]"                                        
 [4] "\\begin{center}"                                           
 [5] ""                                                          
 [6] "  \\hline"                                                 
 [7] " & Turn & Draw & Turn & Draw \\\\ "                        
 [8] "  \\hline"                                                 
 [9] "1 & 1.00 & -1.76 & 6.00 & 0.70 \\\\ "                      
[10] "  2 & 2.00 & 1.58 & 7.00 & 2.57 \\\\ "                     
[11] "  3 & 3.00 & -1.80 & 8.00 & 0.47 \\\\ "                    
[12] "  4 & 4.00 & -2.25 & 9.00 & -0.63 \\\\ "                   
[13] "  5 & 5.00 & 1.99 & 10.00 & -0.35 \\\\ "                   
[14] "   \\hline"                                                
[15] ""                                                          
[16] "\\end{center}"                                             
[17] "\\end{table}"                                                  
 }
\end{tablehere}

这是如此接近。如何让R以正确的方式打印?

cat(x,sep='\n')而不是print(x)

呢?

这对我有用:

x <- print(xtable(my.mat))
x <- gsub("\\\\begin\\{tabular\\}\\{rrrrr\\}", "", x)
