Dear R-helpers,

Please look at the following minimal code.

\documentclass[a4paper]{article}
\begin{document}
<<>>==
library(zoo)
a<-zoo(1:4,order.by=Sys.time()+1:4)
str(a)
@
\end{document}

When I do R CMD Sweave,followed by pdflatex ,and view the final pdf, the
letter surrounding the phrase zoo,

a ***zoo*** series

are messed up.

They are messed up even inside Emacs now that I think of it but not inside
the R Terminal.

How can I fix this inside Sweave / Emacs.

Many thanks,
Ashim
