print of objects in R

Hello,

I have been watching my output as I create functions and do other things 
in r.
One thing I don't like is the [1,] type notation at the beginning of a 
line.  I have been
able to change that to a number such as 1 2 etc.   using 
as.data.frame(object).

How can I stop the printing of a line number and column heading if I 
want to?
I am thinking about publishing and writing of papers.  It is much easier 
to not have to
remove that leading line number when inserting output into papers.

Thank you.

Sincerely,
mmstat
Andrew

xtable in the library xtable does a good job if you are using latex to
write up your results.  For example:
% latex table generated in R 2.8.0 by xtable 1.5-4 package
% Fri Mar 20 13:48:53 2009
\begin{table}[ht]
\begin{center}
\begin{tabular}{rrrrrr}
  \hline
 & 1 & 2 & 3 & 4 & 5 \\
  \hline
1 & -0.45 & 0.25 & -0.42 & -1.64 & -0.45 \\
  2 & 1.39 & 0.06 & 0.08 & 2.12 & 1.39 \\
  3 & 0.49 & -0.78 & -1.28 & -0.45 & 0.49 \\
  4 & -0.11 & -0.81 & 1.48 & 0.30 & -0.11 \\
  5 & 0.12 & -0.11 & -0.14 & 1.50 & 0.12 \\
   \hline
\end{tabular}
\end{center}
\end{table}

Or you could roll your own using for loops and the print function if
this format isn't what you want.

HTH,

Andrew.

Hi Mary,

To print without [1,] use cat() instead of print(). To get rid of the 
row names when printing a data.frame use:

print(data.frame, row.names = FALSE)

To get nice Latex tables, you can use xtable (as the other reply 
suggested). If you want to include it in Word, you can export your data 
using write.table and read it into Excel to make a table for Word.

cheers,
Paul
