lstsetR(Rset = NULL, LineLength = getOption("width"),
        add = getSweaveListingOption("addRset"),
        startS = "\\lstset{", append = TRUE, withRstyle = FALSE)
lstsetRd(Rdset = NULL, LineLength = getOption("width"),
         add = getSweaveListingOption("addRdset"),
         startS = "\\lstset{",
                    append = TRUE)

Arguments
LineLength
numeric number of characters per line for lstset and friends; defaults to getOption("width")
taglist
S3-object of class taglist; arguments for \lstset of TeX package listings.
Rset
object of S3-class taglist or named list of characters; the listings settings for R-code (for \lstset); defaults to NULL.
Rinset
object of S3-class taglist or named list of characters; the listings settings for R-code in environment Sinput; defaults to NULL.
Routset
object of S3-class taglist or named list of characters; the listings settings for R-code in environment Soutput; defaults to NULL.
Rcodeset
object of S3-class taglist or named list of characters; the listings settings for R-code in environment Scode; defaults to NULL.
Rallset
object of S3-class taglist or named list of characters; the listings settings for R-code in environments Sinput, Soutput, Scode, simultaneously; defaults to NULL.
Rdset
object of S3-class taglist or named list of characters; the listings settings for Rd-code (for \lstset); defaults to NULL.
add
boolean; defaults to TRUE; if TRUE, argument list Rset resp. Rdset will be appended to default value lists getSweaveListingOption("Rset") resp. getSweaveListingOption("Rdset") (see below), overwriting respective entries of the default value lists; in case of lstsetRall may be named vector of length 3 with names c("in","out","code").
startS
character; defaults to "\\lstset\{"; what to do by default we use \lstset; an alternative is to use \lstdefinestyle which amounts to "\\lstdefinestyle\{"; in case of lstsetRall may be named vector of length 3 with names c("in","out","code").
append
logical; if TRUE (default) the new settings are appended to the old ones; otherwise they are prepended; in case of lstsetRall may be named vector of length 3 with names c("in","out","code").
withRstyle
logical; if TRUE "style = Rstyle," is prepended.
withOptionsDefAppend
logical: shall definitions from global options (see SweaveListingoptions) be included?
Details

lstset writes out to stdout a call to TeX command \lstset{arg1 = val1, arg2 = val2, .....} and doing so respects a maximal number of characters per line and does not break arg=val tags. lstsetR and lstsetRd expect either objects of S3 class taglist, or lists of named characters as first arguments, which in the latter case are then converted to taglist; both lstsetR and lstsetRd use particular default values to define R resp. Rd output format. More specifically for R code, it uses getSweaveListingOption("Rset"), and for Rd code, it getSweaveListingOption("Rdset"); lstsetRin, lstsetRout, and lstsetRcode are corresponding specialized commands for 'listings' environments Sinput, Soutput, and Scode, respectively. lstsetRall simultaneously sets/modifies settings for 'listings' environments Sinput, Soutput, and Scode. lstsetdefRstyle redefines listings style definition for Rstyle. The output to stdout can be captured in an .Rnw file as

<< lstsetR, results=tex, echo=FALSE>>=
lstsetR()
@
to insert the corresponding \lstset command to the produced TeX file.

Value
