Compile an .Rnw with greek text to pdf

Question

I tried it using the commented out code without success. Can somebody help?

\documentclass[a4paper]{article}
%\usepackage[english,greek]{babel}


%\latintext 
\title{Sweave Example 1}
\author{George Dontas}

\begin{document}

\maketitle

In this example we embed parts of the examples from the
\texttt{kruskal.test} help page into a \LaTeX{} document:

%\greektext 
Αυτό είναι κείμενο στα Ελληνικά
%\latintext
<<eval=TRUE,echo=TRUE,warning=FALSE,message=FALSE,error=FALSE>>=
data(airquality)

kruskal.test(Ozone ~ Month, data = airquality)
@

which shows that the location parameter of the Ozone distribution varies significantly from month to month. Finally we
include a boxplot of the data:

\begin{center}
<<eval=TRUE,echo=FALSE,results='hide',warning=FALSE,message=FALSE,error=FALSE>>=
boxplot(Ozone ~ Month, data = airquality)
@
\end{center}

\end{document}

It might be useful if you add the error message you get into your post. — Jouni Helske, Feb 28 '13 at 15:30
if the Sweave process works fine and the failure occurs in the processing from (La)TeX to PDF, this question would probably be more appropriate at http://tex.stackexchange.com — Ben Bolker, Feb 28 '13 at 15:42

The problem here is not the R but matter of getting latex to play well with Greek. With hat tip to this answer, perhaps the easiest solution is to switch to XeLaTeX compilation and rewrite your file as

\documentclass[a4paper]{article}
\usepackage{fontspec}
\setmainfont{Times New Roman}
\setsansfont{Arial}
\newfontfamily\greekfont[Script=Greek]{Linux Libertine O}
\newfontfamily\greekfontsf[Script=Greek]{Linux Libertine O}
\usepackage{polyglossia}
\setdefaultlanguage{english}
\setotherlanguage{greek}

\title{Sweave Example 1}
\author{George Dontas}

\begin{document}
\maketitle

Ελληνικό κείμενο

In this example we embed parts of the examples from the
\texttt{kruskal.test} help page into a \LaTeX{} document:

...

and so on as before. Then compile with XeLaTeX (latexmk -xelatex file.Rnw will do that).

Thank you! I get the error: The font "Linux Libertine O" cannot be found. – gd047 Mar 03 '13 at 12:13
Hmm.. I changed font to Arial and saved the .rnw using uTF-8 encoding and it worked. – gd047 Mar 03 '13 at 12:19
Ah, that font must have been one of mine. Still, glad it worked. – conjugateprior Mar 03 '13 at 12:23
However, greek text inside R plots (e.g. a plot title in greek) does not appear correctly. Any ideas? – gd047 Mar 03 '13 at 15:37
Adding "dev='cairo_pdf'" in chunk options solves the problem! – gd047 Mar 03 '13 at 17:02
You're way ahead of me here. Is there a good page or blog that covers on latex/greek issues? (Preferably in english or german). It would be handy to have all these things in one place. – conjugateprior Mar 03 '13 at 22:10
I don't know. I found that solution by googling: https://github.com/yihui/knitr/issues/436 – gd047 Mar 04 '13 at 16:18
