Another known issue is the Sweave code chunk may fail when we change the
|
||||
alignment of the chunk paragraph in LyX (using
|
||||
\family sans
|
||||
Paragraph settings
|
||||
\family default
|
||||
), because LyX may add a macro like
|
||||
\family typewriter
|
||||
|
||||
\backslash
|
||||
centering{}
|
||||
\family default
|
||||
before the code chunk without adding a new line, which will lead to a code
|
||||
chunk like this:

||||
\end_layout

|
||||
This is not a legitimate Sweave code chunk, since
|
||||
\family typewriter
|
||||
<<>>=
|
||||
\family default
|
||||
must start in a new line with nothing before it.
|
||||
Therefore we recommend you to double check the real source code via
|
||||
\family sans
|
||||
View\SpecialChar \menuseparator
|
||||
View Source
|
||||
\family default
|
||||
when changing the alignment of a chunk paragraph, and make sure
|
||||
\family typewriter
|
||||
<<>>=
|
||||
\family default
|
||||
appears in a new line.
|
||||
