[R] Sweave output from print.summary.glm is too wide

[Duncan Mackay]

Oops

I forgot to mention ?xtable and ?latex in Frank Harrell's Hmisc or Design 
packages (I cannot remember)

Hi Peter

If all else fails you can make the space between the columns smaller by 
changing the column spacing in latex
by:

\setlength\tabcolsep{3pt}

The default is 7pt. You may have to go a little higher if it looks cramped. 
I have gone down as far as 2pt using a small font size

Also changing the fontsize for the chunk can work wonders eg for small
\begin{small}
<< >>==
R code
@
\end{small}
