I am generating some LaTeX tables using xtable. I'd like to make it so that when I copy and paste the generated table it would look "lined up" in my LaTeX file. Right now I have:
> library(xtable)
> x <- data.frame(matrix(1:6, nrow = 2))
> xtable(x)
% latex table generated in R 3.1.2 by xtable 1.7-4 package
% Fri Jan 23 09:25:22 2015
\begin{table}[ht]
\centering
\begin{tabular}{rrrr}
\hline
& X1 & X2 & X3 \\
\hline
1 & 1 & 3 & 5 \\
2 & 2 & 4 & 6 \\
\hline
\end{tabular}
\end{table}

How can I make the table (at least the 2 rows with real data) look like this? Here all the white spaces before and after & are tabs.
\begin{table}[ht]
\centering
\begin{tabular}{rrrr}
\hline
& X1 & X2 & X3 \\
\hline
1 & 1 & 3 & 5 \\
2 & 2 & 4 & 6 \\
\hline
\end{tabular}
\end{table}
Hackish, but it should work:
library(xtable)
x <- data.frame(matrix(1:6, nrow = 2))
xtab = capture.output(print(xtable(x)))
library(stringr)
tab.xtab = str_replace_all(xtab, pattern = " +\\& +", "\t\\&\t")
# one of these should work, depending on where this is going
cat(tab.xtab, sep = "\n")
paste(tab.xtab, collapse = "\n")
