Hello everyone
I am preparing a document using Sweave in which I want my matrices
to appear as tables. I am running into problems because as my
Rnw files stand, I have to change table entries twice, once for
the matrix and once for the typeset table.
I have lots of material like the following. How can I arrange
my Rnw file so that I only have to change one set of figures
when my numbers change?
One reason I prefer tables here is that the NA entries
appear as "-" in the table, but as "NA" in the Schunk.
Is there a way to make the Schunk typeset NAs
as minuses?
\begin{table}
\centering
\begin{tabular}{|cccc|c|}\hline
\multicolumn{4}{|c|}{brand}&\\ \hline
A&B&C&D&total\\ \hline
2 & 3 & 4 & 1 & 10 \\
0 & 5 & 7 & - & 12 \\
3 & 7 & - & 4 & 14 \\
2 & - & - & 2 & 4 \\ \hline
7&15&11&7&40\\ \hline
\end{tabular}
\caption{snipped caption}
\end{table}

jj <- matrix(c(2, 3, 4, 1,
0, 5, 7, NA,
3, 7, NA, 4,
2, NA, NA, 2
),byrow=TRUE,nrow=4)
jj <- rbind(jj,apply(jj,2,sum,na.rm=TRUE))
jj <- cbind(jj,apply(jj,1,sum,na.rm=TRUE))
jj
