Is it possible that we do not have the full session code and that
attach(df) was executed "off-stage" so to speak, or perhaps the OP is
following an example where attach(df) was executed several pages
earlier. The column names are being treated in the code as first class
objects.

It would be easier to help if you made your example
reproducible (what is
IDADE and where does it come from?).

Hi,
in Latex I get the table using:
\begin{table}[H]
\centering
\renewcommand{\arraystretch}{1.3}
\setlength{\tabcolsep}{18pt}
\begin{tabular}{cc} \hline
Idade & Frequência \\ \hline
$18 \vdash 26$ & 11 \\
$26 \vdash 34$ & 8 \\
$34 \vdash 42$ & 26 \\
$42 \vdash 50$ & 20 \\
$50 \vdash 58$ & 23 \\
$58 \vdash 66$ & 30 \\
$66 \vdash 74$ & 17 \\
$74 \vdash 82$ & 9 \\
$82 \vdash 90$ & 2 \\
$90 \vdash 98$ & 2 \\ \hline
\end{tabular}
\end{table}
I tried get a similar table using Sweave, but it isn't
work.
The commands are:
<<>>=
Idade.tb = cut(IDADE,
breaks=c(18,26,34,42,50,58,66,74,82,90,98), right=F)
cbind(table(Idade.tb))
@
<<idades, echo=F, results=hide>>=
Idade.tb = cut(IDADE,
breaks=c(18,26,34,42,50,58,66,74,82,90,98), right=F)
Idade_freq = cbind(table(Idade.tb))
medias.idades = tapply(IDADE, SEXO, mean)
@
<<idade, echo=F, results=verbatim>>=
Idade_freq
@
or
<<>>=
xtable(Idade_freq)
@
but they are not the way I want.
Any suggestions?
