R help - Mar 2012 - How to draw table in Latex without using xtable?

Hi, 

I am working on table suing R and Latex.  I am writing .Rnw file first in
which i m reading input file and storing into dataframe. After filtering
certain values from this dataframe. I am planning to display it. I don't
want to use xtable since i need to change column names.  

*Sample .Rnw file*

@
<<echo=FALSE>>cat("\begin{table}[ht]")
cat("\begin{center}")
cat("\begin{tabular}{lrrrrr}")
cat  ("\hline")
cat ("& Df & Sum Sq & Mean Sq & F value & Pr($>$F)
\\")
cat  ("\hline")
cat("block       & 5 & 343.29 & 68.66 & 4.45 & 0.0159
\\")
cat  ("N           & 1 & 189.28 & 189.28 & 12.26 &
0.0044 \\")
cat  ("P           & 1 & 8.40 & 8.40 & 0.54 & 0.4749
\\")
cat  ("K           & 1 & 95.20 & 95.20 & 6.17 & 0.0288
\\")
cat  ("N:P         & 1 & 21.28 & 21.28 & 1.38 & 0.2632
\\")
cat  ("N:K         & 1 & 33.13 & 33.13 & 2.15 & 0.1686
\\")
cat  ("P:K         & 1 & 0.48 & 0.48 & 0.03 & 0.8628
\\")
cat  ("Residuals   & 12 & 185.29 & 15.44 &  & 
\\")
cat   ("\hline")
cat("\end{tabular}")
cat("\end{center}")
cat("\end{table}")
@

But i am getting error  cat("\" not supported.  In my case tabular
values
are variable. How can i fix my pblm?

Regards

I don't know xtable but you could try escaping the backslashes in your
strings.
cat("\\begin{table}[ht]") etc.

Regards!

You can use xtable() or latex() and then edit the columns names in the
generated .tex file.  That is a much better plan than reinventing either of
those functions.
