highlight (version 0.4.7)

highlight-package: Syntax Highlighter for R

Description

Syntax highlighter for R based on output from the R parser

See Also

The main function of the package is highlight.

highlight delegates rendering the document to renderers, such as the renderer_latex or renderer_html and is helped by a detective to make sense of the results from the parser. The package ships a simple_detective.

The package also defines a custom sweave driver (HighlightWeaveLatex) for latex based on the standard sweave latex driver (RweaveLatex) using highlight to perform syntax highlighting of R code chunks.

Examples

## Not run: 
# tf <- tempfile()
# dump( "glm" , file = tf )
# 
# # rendering in html
# highlight( tf, output = stdout(),
# 	renderer = renderer_html() )
# 
# # rendering in latex
# highlight( tf, output = stdout(),
# 	renderer = renderer_latex() )
# 
# # Sweave driver using syntax highlighting
# if( require( grid ) ){
# 	v <- vignette( "grid", package = "grid" )$file
# 	file.copy( v, "grid.Snw" )
# 	Sweave( "grid.Snw", driver= HighlightWeaveLatex() )
# 	system( "pdflatex grid.tex" )
# 	if (.Platform$OS.type == "windows"){
# 		shell.exec( "grid.pdf" )
# 	} else {
# 		system(paste(shQuote(getOption("pdfviewer")), "grid.pdf" ),
# 			wait = FALSE)
