# [Rd] Sweave trims console output in "tex" mode

Hi

In the example .Rnw file below, only the newline between c and d is
visible in the resulting .tex file after running R CMD Sweave. What is
the reason for this behavior? Newlines are important in LaTeX and should
be preserved. In particular, this behavior leads to incorrect LaTeX code
generated when using tikz(console=TRUE) inside a Sweave chunk, as shown
in the tikzDevice vignette.

A similar question has been left unanswered before:
https://stat.ethz.ch/pipermail/r-help/2010-June/242019.html . I am well
aware of knitr, I'm looking for a solution for Sweave.

Cheers
