使用xtable重写rownames重命名重复项

Question

我希望xtable不要覆盖我重复的rowname条目.考虑以下MWE:

> require(xtable)
> foo <- matrix(0, 2,2)
> rownames(foo) = rep("bar", 2)
> foo
    [,1] [,2]
bar    0    0
bar    0    0
> xtable(foo)
% latex table generated in R 2.15.0 by xtable 1.7-0 package
% Fri Jun 22 13:59:36 2012
\begin{table}[ht]
\begin{center}
\begin{tabular}{rrr}
  \hline
 & 1 & 2 \\ 
  \hline
1 & 0.00 & 0.00 \\ 
  2 & 0.00 & 0.00 \\ 
   \hline
\end{tabular}
\end{center}
\end{table}
Warning message:
In data.row.names(row.names, rowsi, i) :
  some row.names duplicated: 2 --> row.names NOT used

而不是让rownames为1和2,我希望它们是我原来的"酒吧"和"酒吧".有没有办法超越xtable的重复替换方案？

Answer 1

这是xtable解决方案(以非常紧凑的形式):

> print(xtable(data.frame(row = rownames(foo),data.frame(foo))),include.rownames = FALSE)
% latex table generated in R 2.14.2 by xtable 1.6-0 package
% Fri Jun 22 14:24:59 2012
\begin{table}[ht]
\begin{center}
\begin{tabular}{lrr}
  \hline
row & X1 & X2 \\ 
  \hline
bar & 0.00 & 0.00 \\ 
  bar & 0.00 & 0.00 \\ 
   \hline
\end{tabular}
\end{center}
\end{table}

这仍然会发出警告,并且很难使列标题正确.另一种选择是使用latex从Hmisc包,这是更灵活了不少(但也更复杂,你可以关闭多光柱的东西):

library(Hmisc)
> latex(foo,file = "")
% latex.default(foo, file = "") 
%
\begin{table}[!tbp]
\begin{center}
\begin{tabular}{lrr}
\hline\hline
\multicolumn{1}{l}{foo}&\multicolumn{1}{c}{}&\multicolumn{1}{c}{}\tabularnewline
\hline
bar&$0$&$0$\tabularnewline
bar&$0$&$0$\tabularnewline
\hline
\end{tabular}
\end{center}
\end{table}

对不起,简短的评论.我当时抱着一个婴儿.
