Dear list,
I using R as the statistical package for my dissertation in political
sciences and I am using Sweave for documenting the work done for the
creation of my dataset. However, I have a problem with Sweave (which is
great, by the way) which is (hopefully) easy to solve:
I want Sweave to "echo" my code, so that the R source code of the code
chunks appears in the Latex document. However, since I am using several
$ signs per line, as in the example line below, Latex interprets this as
a math environment, despite the fact that the $ signs are within the
{Sinput} environment. The problem now is that I sometimes have an
unequal number of $ signs in an input line, so that LaTex thinks that
all of the following "normal" text is still part of the math
environment, and formats it accordingly.
This is an example input line:
Pre_Year <- MyMain3$Con_Stat[MyMain3$MyID==ID_Count[i] &
MyMain3$MyYear==Count_Years[y-1]]
where I have three $ sings, and LaTex thinks that everything following
the last $ sign is still part of a formula.
Sinput is a verbatim environment, so LaTeX should not try to interpret
that line, if it's in an Sweave block. Are you using the correct
Sweave.sty file to define it?
A real reproducible example (i.e. a complete input file that fails)
would be a lot easier to diagnose.

I have two question now:
1. Is there any way to solve the problem within Sweave itself, e.g.
through setting options?
2. If not: is there a way to generally turn off the math mode in LaTex
in the preamble, since I generally don't need it? (Maybe I should better
post this in the LaTex mailing list, but maybe some people here had
similar problems)
Thanks for all comments!
Best,
Christian
PS: I tried to replace all $ signs by \$, but this did not work either
and caused many LaTex errors.
