No, no changes in 2.1 with respect to that problem. I have plans for a
solution for this problem, but won't have time for it before summer
break - in 2.2 there should be a fix for it.

Best,

[R] input line length in Sweave

2005-05-24 Thread Woodrow Setzer 

I am having trouble in Sweave with input line lengths.  For example, I may have 
in my input file the chunk

=
BrainSections -
  levels(AggData$sctn)[grep(
(^BRAIN)|(^WHOLEBRAIN)|(LEFT HEMISPHERE)| (HALFBRAIN),
levels(AggData$sctn))]

@ 

This is translated in the tex file:

\begin{Sinput}
 BrainSections - levels(AggData$sctn)[grep((^BRAIN)|(^WHOLEBRAIN)|(LEFT 
 HEMISPHERE)| (HALFBRAIN), 
+ levels(AggData$sctn))]
\end{Sinput}

The problem is that the line produced is too long.  I read the answer to the 
Sweave FAQ question 13 (How can I change the line length of S input and 
output?) to mean that options(width) controls both input and output; however, 
the first code chunk in the above example contains 
=
options(width=66)

Is there a way to get Sweave to wrap long input lines better, or get it to use 
my own formatting of the input?  I realize I can edit the output tex file, but 
that is impractical in my application (too many).

suppose one possible answer is that this is fixed in 2.1.0; I cannot switch 
right now).
