Dear R-users
I am trying to understand how Sweave works by running some simple examples. In
the example I am working with there is a chunk where the R-commands related to
plotting a figure are placed. When running R CMD Sweave … , pdflatex the
output is a portrait figure. I wonder whether it would be possible to change
the orientation to landscape (not in the latex file but in Rnw file).
Sweave can change the height and width of the figure so it is more
landscape-shaped (width > height) using options at the start of the chunk.
Rotating a figure is something LaTeX needs to do: you would tell Sweave
to produce the figure but not include it, then use \includegraphics{}
with the right option to rotate it.
For example:
<<Myfig, fig=TRUE, include=FALSE, width=7in, height=4in>>=
plot(rnorm(100))
@
\includegraphics[angle=90,width=0.8\textheight]{Myfig}
This is untested, and you'll need to consult a LaTeX reference for
rotating the figure caption, etc.
