[ESS] Rnw-mode no line break

[Wang, Zhu]

Dear all,

I am having trouble with my Rnw mode file format using Xemacs. For example, the following file has no line break but when I have other mode I do have line break.

\documentclass[a4paper]{article}\title{Chronic Alcoholism and Bone Mineral Density}\author{Center for Biostatistics}\begin{document}\maketitle<<echo=false,results=hide>>=library(foreign)alco.data
..................................................

Below if my init.el and I also have difficult to find who Rnw was set up since commenting out the bottom doesn't work and I still have Rnw-mode.

Thanks for any help.

Zhu Wang
