这就是我想在 LyX 中实现的目标：
<<A-simple-plot>>= x<-rnorm(10) y<-rnorm(10) plot(x,y) @
\ begin { knitrout } \ d e f i n e c o l o r { shadecolor }{ rgb }{0.969 , 0.969 , 0.969}\ color { f g c o l o r }\ begin {kframe} \ begin { a l l t t } \ hlstd {x}\hlkwb{<=}\hlkwd{rnorm}\ hlstd {(}\hlnum{10}\ hlstd {)} \ hlstd {y}\hlkwb{<=}\hlkwd{rnorm}\ hlstd {(}\hlnum{10}\ hlstd {)} \hlkwd{ plot }\ hlstd {(x , y)} \end{ a l l t t } \end{kframe} \ includegraphics [ width=\maxwidth ]{ f i g u r e /unnamed=chunk=3=1} \end{ knitrout }
这显然不是我想要的...我还没有检查 Verbatim 包...
有人可以告诉我如何解决这个问题吗？

Minimal Working Example with Knitr Program Listing using Algorithm Floats

\begin_layout Abstract
This is a minimal working example of a LyX article that aims at including
\begin_inset ERT
status open
\begin_layout Plain Layout
\backslash
textsf{R}
\end_layout
\end_inset
and executing
\begin_inset ERT
status open
\begin_layout Plain Layout
\backslash
textsf{R}
\end_layout
\end_inset
code chunks and showing a program listing of an
\begin_inset ERT
status open
\begin_layout Plain Layout
\backslash
textsf{R}
\end_layout
\end_inset
code chunk without executing it.
For this to happen the module Rnw (knitr) needs to be added to this document
(Document ▷ Settings ▷ Modules ▷ Rnw (knitr)) as well as have knitr installed
in
\begin_inset ERT
status open
\begin_layout Plain Layout
\backslash
textsf{R}
\end_layout
\end_inset
.
The path
\begin_inset ERT
status open
\begin_layout Plain Layout
\backslash
textsf{R}
\end_layout
\end_inset
needs to be correctly specified.
The Document Class is Article (Standard Class.) Let's get to the problem
at hand.

\begin_inset ERT

That one ran OK.
Let's create a program listing to display the complete code of the above
chunk using Figure (See
\begin_inset CommandInset ref
LatexCommand ref

\end_inset
), Table (See
\begin_inset CommandInset ref

\end_inset
) and Algorithm floats:
\end_layout

\begin_inset Float figure
wide false
sideways false
status open
\begin_layout Plain Layout
\begin_inset listings

\begin_layout Plain Layout

This was the process: Insert ▷ Float ▷ Figure, Table, Algorithm whichever
applicable.
Then, inside the float, Insert ▷ Program Listing...
I just copy-pasted the code inside the knitr chunk...
Preview doesn't render the floats correctly...

@scottkosty 我发现了一个非常糟糕的解决方法，但可以在算法浮动内使用无框架框来解决这个问题。这是一个最小的例子：

\begin_layout Abstract
This is a horrible workaround to solve a question I asked at
\begin_inset Flex URL
status open
\begin_layout Plain Layout
https://stackoverflow.com
\end_layout
\end_inset
where I wanted to add an algorithm float with a program listing inside
with
\begin_inset ERT
status open
\begin_layout Plain Layout
\backslash
textsf{R}
\end_layout
\end_inset
knitr code not to be executed.
I found that the module Rnw was interfering with what I wanted.
Thus, a workaround to be able to display the whole code using an algorithm
float a plain box from LyX.
In this minimal working example I show how I achieved a less than optimal
solution.
