- withOwnFileSection
- logical: Does one want to use an own definition file/
section to define
Sinput,Soutput,Scodeenvironments; ifTRUEyou should write some \include directive to include your own definitions / or write them in your ‘.Rnw’ file. - withVerbatim
- logical of length 3 (filled by recycling if of shorter length)
either named ("Sinput", "Soutput", "Scode") or taken in
order (Sinput, Soutput, Scode):
Should we use Verbatim from TeX package 'fancyvrb'
(i.e. the original
"\DefineVerbatimEnvironment{Sinput}{Verbatim}" by
Fritz Leisch) or just TeX package 'listings'
(i.e. we define our own
Sinputenvironment based on 'listings' command 'lstnewenvironment'; this option is due to a suggestion by Andrew Ellis (thank you!). - withSchunkDef
- logical: shall environment
Schunkbe defined? - gin
- logical: shall we use
gin - ae
- logical: shall we use
ae - LineLength
- numeric; defaults to 80
- Rset
- list or taglist; defaults to global option
"Rset" - Rdset
- list or taglist; defaults to global option
"Rdset" - Rin
- list or taglist; format string for R input code; defaults to global option
"Rin" - Rout
- list or taglist; format string for R output code; defaults to global option
"Rout" - Rcode
- list or taglist; format string for R code; defaults to global option
"Rcode" - Rcolor
- numeric of length 3; [color for R-input-code] defaults to global option
"Rcolor"; rgb coordinates of the color in which to print R-code - RRecomdcolor
- numeric of length 3; [color for R-symbols from recommended packages]
defaults to global option
"RRecomdcolor"; rgb coordinates of the color in which to print R-code - Rbcolor
- numeric of length 3; [color for R-symbols from intermediate packages] defaults to global option
"Rbcolor"; rgb coordinates of the color in which to print R keywords induced by intermediate packages. - Routcolor
- numeric of length 3; [color for R-output-code] defaults to global option
"Rout"; rgb coordinates of the color in which to print R output - Rcommentcolor
- numeric of length 3; [color for R-comments] defaults to global option
"Rcomment"; rgb coordinates of the color in which to print comments in R-code - pkg
- character; name of the packageto be described (e.g. in a vignette);
defaults to global option
"pkg" - pkv
- character; package version to be described (e.g. in a vignette);
defaults to global option
"pkv" - fileCommand
- character; the TeX code to define TeX command
\file - pkgCommand
- character; the TeX code to define TeX command
\pkg - lib.loc
- location of a local library in which the described package resides
Details
SweaveListingPreparations
writes a corresponding preamble to the ‘.Rnw’-file for the simultaneous use
of Sweave and package listings; note that so far, even if you do not want to
use the default style file ‘Sweave.sty’, the lines
%\usepackage{Sweave}
\SweaveOpts{keep.source=TRUE}
still have to appear in the ‘.Rnw’ file --- before the corresponding
SweaveListingPreparations-chunk.
The TeX code inserted by SweaveListingPreparations sets colors,
requires TeX-package ‘listings’,
defines listings-settings for ‘.R’- and ‘.Rd’-code.
For ‘.Rd’ files it uses a new 'listings'-language definition file,
‘Rdlisting.sty’ to be found in subfolder ‘TeX’ in the
SweaveListingUtils package folder.
SweaveListingPreparations is to be called in an ‘.Rnw’ file and
[re-]defines Sinput,
Soutput, Scode environments for use with TeX-package ‘listings’,
defines commands \code, \file, \pkg and sets
the corresponding package version.
The default values are taken from
SweaveListingOptions.
The output to stdout can be captured in an ‘.Rnw’ file as
<< lstPreamble, results=tex, echo=FALSE>>= require(SweaveListingUtils) SweaveListingPreparations() @to insert the corresponding preamble parts to the produced TeX file. If you one want to use destinct keywordstyles for packages loaded by
require or library without adding extra arguments
to these commands (and hence displaying the actual R code),
you have to set up a global formatting matrix
.tobeDefinedPkgs by setToBeDefinedPkgs.
