Arguments
withOwnFileSection
logical: Does one want to use an own definition file/ section to define Sinput, Soutput, Scode environments; if TRUE you 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 Sinput environment based on 'listings' command 'lstnewenvironment'; this option is due to a suggestion by Andrew Ellis (thank you!).
withSchunkDef
logical: shall environment Schunk be 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.
