SweaveListingPreparations: SweaveListingPreparations

Description

helping tool for writing the corresponding TeX preamble commands to integrate Sweave and package listings

Usage

SweaveListingPreparations( withOwnFileSection = FALSE, withVerbatim = FALSE, withSchunkDef = TRUE, gin = TRUE, ae = TRUE, LineLength = getOption("width"), Rset = getSweaveListingOption("Rset"), Rdset = getSweaveListingOption("Rdset"), Rin = getSweaveListingOption("Rin"), Rout = getSweaveListingOption("Rout"), Rcode = getSweaveListingOption("Rcode"), Rcolor = getSweaveListingOption("Rcolor"), RRecomdcolor = getSweaveListingOption("RRecomdcolor"), Rbcolor = getSweaveListingOption("Rbcolor"), Routcolor = getSweaveListingOption("Routcolor"), Rcommentcolor = getSweaveListingOption("Rcommentcolor"), pkg = getSweaveListingOption("pkg"), pkv = getSweaveListingOption("pkv"), fileCommand = getSweaveListingOption("fileCommand"), pkgCommand = getSweaveListingOption("pkgCommand"), lib.loc = NULL)

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

Value

Acknowledgement

The author wants to thank Frank E. Harrel and Andrew Ellis for very valuable suggestions to enhance this package.

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.

Examples

SweaveListingPreparations()
