[Tex/LaTex] R Chunk Code within Enumeration Environment with knitr in LyX

#enumerateknitrlyxsweave

I need R Chunk Code within Enumeration Environment in Rnw file. The following .Rnw document works fine.

\documentclass{article}
\begin{document}

\begin{enumerate}
\item The quick brown fox jumps over the lazy dog.\\
<<boring-random>>=
1:4
@
\\ The quick brown fox jumps over the lazy dog.

\item The quick brown fox jumps over the lazy dog.

\end{enumerate}

\end{document}

But when I import the same file to LyX, the R Chunk Code delimiter @ combines with text (See image below). I would highly appreciate if you guide me how to put R Chunk Code within Enumeration Environment in LyX using LyX built-in Enumeration Environment. Thanks

You've "kind of" run into a LyX bug/feature enhancement http://www.lyx.org/trac/ticket/8875

The workaround is simple: add an empty line at the end of your ERT box, after "@".

I say "kind of" above because once that ticket is fixed (possibly in 2.2.0 version which won't be out for a while), I'm not sure we will activate that option for ERT. It will be activated for the Chunk inset, which if you're using LyX 2.1.1 you can get by going to Insert > Custom Insets > Chunk. It's a matter of preference whether to use that inset or ERT. Note that the knitr author, also a LyX user, prefers to use ERT. I prefer to use the Chunk inset.
