Sweave and Rnews

- I have some long lines of code in schunk. I did not find any way to
cut them in the Rnw file and they appear out of the column in the dvi
file. The only solution I found is to cut these lines in the tex file
generated by Sweave. Is there a more elegant and automatic solution to
this problem?

Hello list,

I am writing a paper for Rnews. I use Sweave to do it. I did not find 
information about writing a paper for Rnews using Sweave and have some 
questions:
- Is there a problem to use the environment 'Sinput' in the place of 
'example' or 'smallexample'. It works fine but perhaps there are some 
technical/editorial problems ?

Thanks in advance.
