R code can be mixed into a LaTeX document, and will be executed in R when

the document is compiled; the results are written into the TeX output.

Since LyX 2.0, Sweave can be used out of the box with any document class
|
|
using the
|
|
\family sans
|
|
Sweave
|
|
\family default
|
|
module.
|
|
We can add the
|
|
\family sans
|
|
Sweave
|
|
\family default
|
|
module to a LyX document from
|

In this manual, we demonstrate some common features of Sweave and explain
|
|
how the module works.

\begin_layout Standard
|
|
The
|
|
\family sans
|
|
Sweave
|
|
\family default
|
|
module depends on the executable
|
|
\family typewriter
|
|
Rscript
|
|
\family default
|
|
, so it has to be in the
|
|
\family sans
|
|
PATH
|
|
\family default
|
|
variable of the system.
|
|
It is usually not a problem for Linux and Mac OS users, but may be confusing
|
|
to Windows users; if you do not understand what is
|
|
\family sans
|
|
PATH
|
|
\family default
|
|
under Windows, you may either use the R script
|
|
\family sans
|
|
add-R-path-win.R
|
|
\family default
|
|
in the repository

to change it automatically (not recommended; you should learn
|
|
\family sans

anyway), or go to

After you have done these changes, you need to reconfigure LyX by
|
|
\family sans
|
|
Tools\SpecialChar \menuseparator
|
|
Reconfigure
|
|
\family default
|
|
.
|
|
If
|
|
\family typewriter
|
|
Rscript
|
|
\family default
|
|
is not present in
|
|
\family sans
|
|
PATH
|
|
\family default
|
|
, the
|
|
\family sans
|
|
Sweave
|
|
\family default
|
|
module will be unavailable.
|
|
It is recommended to use the latest version of R, since Sweave is still
|
|
being updated.
|
|
Another dependency is introduced by the LaTeX style file
|
|
\family sans
|
|
Sweave.sty
|
|
\family default
|
|
which is shipped with R under this path (it is not on CTAN):

|

|
\begin_layout Standard
|
|
MikTeX users may add the texmf directory to the list of root directories
|
|
in MikTeX through MikTeX settings.
|
|
Further note that
|
|
\family sans
|
|
Sweave.sty
|
|
\family default
|
|
depends on the
|
|
\series bold
|
|
fancyvrb
|
|
\series default
|
|
package and
|
|
\emph on
|
|
may
|
|
\emph default
|
|
depend on
|
|
\series bold
|
|
ae
|
|
\series default
|
|
.
|
|
If LyX cannot find
|
|
\family sans
|
|
Sweave.sty
|
|
\family default
|
|
, it will directly copy from R, so the Sweave module works even if you do
|
|
not know where is this style file.

Sweave Examples

|
\end_layout
|
|
|
|
\begin_layout Standard
|
|
Before we write an Sweave document, we can set some Sweave options; the
|
|
command is
|
|
\family typewriter
|
|
|
|
\backslash
|
|
SweaveOpts{}
|
|
\family default
|
|
in Sweave and it can be inserted in a LyX document by
|
|
\family sans
|
|
Insert\SpecialChar \menuseparator
|
|
Custom Insets\SpecialChar \menuseparator
|
|
Sweave Options
|
|
\family default
|
|
, or just use TeX code to write it (
|
|
\family sans
|
|
Insert\SpecialChar \menuseparator
|
|
TeX Code
|
|
\family default
|
|
).
|
|
For example, we can set a global option
|
|
\family typewriter
|
|
echo=FALSE
|
|
\family default
|
|
in the beginning of a document to suppress all R code (by default, both
|
|
R code and its output will show up in the LaTeX document).
|
|
|
|
\end_layout
|
|
|
|
\begin_layout Standard
|
|
To write R code in LyX, you can first switch to the
|
|
\family typewriter
|
|
Chunk
|
|
\family default
|
|
environment in the layout styles list (droplist in the top-left corner
|
|
in the toolbar), or you can simply open a TeX code environment and write
|
|
Sweave code chunks in it.
|
|
The latter approach is recommended since it is more stable.
|
|
\end_layout
|
|
|
|
\begin_layout Standard
|
|
Some R options can be useful to the Sweave output as well, e.g.
|
|
|
|
\family typewriter
|
|
width
|
|
\family default
|
|
and
|
|
\family typewriter
|
|
useFancyQuotes
|
|
\family default
|
|
.
|
|
The former option can adjust the width of the output, and the latter can
|
|
avoid a common problem with quotes.
|
|
Users are encouraged to read the Sweave manual in R for more details.

|
|
The

module uses the
|
|
\family sans

|
|
General users do not need to know clearly what they mean, but here we need
|
|
to explain a few issues in the R code:
|
|
\end_layout
|
|
|
|
\begin_layout Enumerate
|
|
the encoding string of the LyX document is passed to R as an command line
|
|
option; possible values are
|
|
\family typewriter
|
|
ISO-8859-15
|
|
\family default
|
|
and
|
|
\family typewriter
|
|
UTF-8
|
|
\family default
|
|
, etc.
|
|
The encoding is used for R to read the
|
|
\family sans
|
|
Rnw
|
|
\family default
|
|
document correctly.
|
|
\end_layout
|
|
|
|
\begin_layout Enumerate
|
|
the R code chunks in the Sweave document are executed under the directory
|
|
of the LyX document (if you are not sure, put
|
|
\family typewriter
|
|
getwd()
|
|
\family default
|
|
in a code chunk to see what is the current working directory).
|
|
In this case, you can put data files under the same directory and use relative
|
|
paths in R to guarantee reproducibility, i.e.
|
|
we do not need to write hard-coded paths which may not exist in other systems.
|
|
\end_layout
|
|
|
|
\begin_layout Enumerate
|
|
if LaTeX cannot find
|
|
\family sans
|
|
Sweave.sty
|
|
\family default
|
|
, this R script will copy it to the temporary directory automatically where
|
|
the LaTeX compilation takes place.
|
|
\end_layout
|
|
|
|
\begin_layout Enumerate
|
|
Sweave will use the filename of the Rnw file as the prefix string for the
|
|
graphics output by default; one known issue (
|
|
\begin_inset CommandInset href
|
|
LatexCommand href
|
|
name "#7551"
|
|
target "http://www.lyx.org/trac/ticket/7551"
|
|
|
|
\end_inset
|
|
|
|
) is that if the filename (without extension) contains dots, LaTeX can fail
|
|
to deal with such files in
|
|
\family typewriter
|
|
|
|
\backslash
|
|
includegraphics{}
|
|
\family default
|
|
.
|
|
Therefore, we have set the default value of the prefix to be the filename
|
|
with all the dots being replaced by
|
|
\begin_inset Quotes eld
|
|
\end_inset
|
|
|
|
-
|
|
\begin_inset Quotes erd
|
|
\end_inset
|
|
|
|
.
|
|
We can also solve this problem in Sweave directly: set the Sweave option
|
|
|
|
\family typewriter
|
|
prefix.string
|
|
\family default
|
|
to be a character string without dots, and this option will override the
|
|
default value.
|
|
\end_layout
|
|
|
|
\begin_layout Standard
|
|
We have pre-specified an option
|
|
\family typewriter
|
|
noae
|
|
\family default
|
|
for the Sweave package.
|
|
This option stops Sweave from loading these two packages:

|
|
|
|
\begin_layout Standard
|
|
LyX can deal with the font encoding by default, so there is no need to ask
|
|
Sweave to do this (furthermore, this may bring clashes of package options);
|
|
besides, the users can load the
|
|
\series bold
|
|
ae

|

package by themselves in the preamble if needed.

alignment of the chunk paragraph in LyX (using

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.
|
|
This explains why we manually added an empty line in the code chunk in

How to use Sweave with beamer?
|
|
\end_layout
|
|
|
|
\begin_layout Standard
|
|
You will end up with LaTeX errors if you use Sweave in normal beamer slides
|
|
in LyX; the reason is the beamer frame that contains verbatim R code.
|
|
The solution is to use a
|
|
\emph on
|
|
FragileFrame
|
|
\emph default
|
|
instead of a normal
|
|
\emph on
|
|
Frame
|
|
\emph default
|
|
, or to pass the option
|
|
\family typewriter
|
|
fragile
|
|
\family default
|
|
to the frame title via
|
|
\family sans
|
|
Insert\SpecialChar \menuseparator
|
|
Frame Options
|
|
\family default
|

Can I define my own R script to compile the Rnw document?
|
|
\end_layout
|
|
|
|
\begin_layout Standard
|
|
Yes, of course.
|
|
First you need to understand how the R script
|
|
\family typewriter
|
|
$$s
|
|
\family sans
|
|
/scripts/lyxsweave.R
|
|
\family default
|
|
works, which was introduced previously, and we recommend you to read the
|
|
R source code as well (on how R takes the paths and uses
|
|
\emph on
|
|
Sweave()
|
|
\emph default
|
|
to handle the Rnw document).
|
|
Then you put your customized
|
|
\family sans
|
|
lyxsweave.R
|
|
\family default
|
|
under the
|
|
\family sans
|
|
scripts
|
|
\family default
|
|
directory of your
|
|
\emph on
|
|
user directory
|
|
\emph default
|
|
(again, see
|
|
\family sans
|
|
Help\SpecialChar \menuseparator
|
|
About LyX
|
|
\family default
|
|
).
|
|
Note LyX will check the
|
|
\emph on
|
|
user directory
|
|
\emph default
|
|
before going to its own
|
|
\emph on
|
|
library directory
|
|
\emph default
|
|
; if an R script
|
|
\family sans
|
|
lyxsweave.R
|
|
\family default
|
|
is found in the user directory, it will be used.
|
|
It is not recommended to hack the script under the LyX library directory
|
|
directly, since updating LyX will override you modified script (the user
|
|
directory will not be affected).

Beside the support for the official Sweave in R, the

\series bold

\series default

package is also supported, which is an alternative tool to Sweave; the

corresponding module is named
