[R] Problems with xtable?

[Silvano Cesar da Costa]

Hi,

I'm using Sweave to create some tables. My code is:

<<label=Q1, echo=FALSE, results=tex>>=
tab1 = table(DISCIPLINA, Q1)
tab1.prop = round(addmargins(100*prop.table(tab1, 1),
FUN=list(Total=sum)), 2)
tab1.txt = xtable(tab1.prop, align="l|rrrrrr", label='Q1',
caption=c("Apresentação da proposta de programa a ser desenvolvida na
disciplina", "Q1"))
print(tab1.txt, format.args=list(big.mark = ".", decimal.mark = ","),
caption.placement='top', table.placement='H')
@


but, the output is

Margins computed over dimensions
in the following order:
1: DISCIPLINA
2: Q1
% latex table generated in R 3.0.0 by xtable 1.7-1 package

\begin{table}[H]
\centering
\caption[Q1]{Apresentação da proposta de programa a ser desenvolvida na
disciplina}
\label{Q1}
\begin{tabular}{l|rrrrrr}
  \hline
 & 1 & 2 & 3 & 4 & 5 & Total \\
  \hline
6BAV039 & 5,45 & 20,00 & 40,00 & 29,09 & 5,45 & 100,00 \\
  6BIO029 & 1,85 & 1,85 & 31,48 & 37,04 & 27,78 & 100,00 \\
  6BIO030 & 0,00 & 0,00 & 5,45 & 45,45 & 49,09 & 100,00 \\
  6BIO031 & 0,00 & 1,89 & 45,28 & 30,19 & 22,64 & 100,00 \\
  6BIQ014 & 0,00 & 0,00 & 9,26 & 42,59 & 48,15 & 100,00 \\
  6CIF023 & 1,85 & 3,70 & 20,37 & 42,59 & 31,48 & 100,00 \\
  6EMA024 & 1,85 & 9,26 & 25,93 & 38,89 & 24,07 & 100,00 \\
  6HIT011 & 0,00 & 0,00 & 3,70 & 27,78 & 68,52 & 100,00 \\
  6MOR012 & 0,00 & 0,00 & 41,82 & 47,27 & 10,91 & 100,00 \\
  6PAT013 & 0,00 & 5,56 & 29,63 & 44,44 & 20,37 & 100,00 \\
  6SOC016 & 3,64 & 9,09 & 38,18 & 29,09 & 20,00 & 100,00 \\
  Total & 14,65 & 51,35 & 291,11 & 414,43 & 328,47 & 1.100,00 \\
   \hline
\end{tabular}
\end{table}


and I don't want this output

Margins computed over dimensions
in the following order:
1: DISCIPLINA
2: Q1


How can I get out it?


Thanks,
