View source: R/keywordsStyle.R
sets up / updates a table of keywordstyles to different packages
1 | changeKeywordstyles(pkgs, keywordstyles)
|
pkgs |
character; the packages for which keywordstyle information is to be changed |
keywordstyles |
character or missing; the corresponding keywordstyle format
strings; if missing the corresponding option |
Before changing the keywordstyles, we first check whether the corresponding
package is registered at all —by looking up the
(non-exported) vector object .alreadyDefinedPkgs
, which is hidden in the
namespace of this package.
For changing the keywordstyle, we write out a
1 2 3 | \lstdefinelanguage{R}%
{keywordstyle=[<order number>]<keywordstyle as format string>,%
}
|
directive to standard out, where <keywordstyle as format string>
is a string containing any sequence of TeX formatting commands like
"\\bfseries\\footnotesize"
. Note that backslashes have to be escaped.
and <order number>
is just num+2
where num
is the index of the package in the .alreadyDefinedPkgs
vector.
For use in an .Rnw
file, the call to lstsetlanguage
should be
wrapped into a corresponding Sweave chunk in the form
1 2 3 | << /chunkname/, results=tex, echo=FALSE>>=
changeKeywordstyles( ..... )
@
|
for example
1 2 3 4 | <<distrRegisterKeywords, results=tex, echo=FALSE>>=
changeKeywordstyles(pkgs = "distr",
keywordstyles = "\\bfseries\\color{blue}")
@

invisible()
