Syntax Highlighting for R scripts?

When looking at a script, or script snippet, I find it very helpful to see syntax highlighting. I am an addict of highlighting. However, it is difficult to get demo scripts, or script snippets highlighted. One possible solution might be this:
http://alexgorbatchev.com/SyntaxHighlighter/
which currently lacks R support (and its wish list forum has been closed due to spam) but it is customizable. Possibly, building an R highlighter - and particularly one that understands OpenMx functions - would be useful? Or perhaps someone has another solution?
I am thinking that syntax highlighting in the documentation as well as in demo, models/nightly etc might help - as long as one can still cut & paste or download the scripts for use. I wouldn't want that broken.
Kate does this
I assume other editors do this too.

Good point that!
library(OpenMx)
which would have the (possible) advantage of working consistently for users of different editors, systems etc. Textmate formatted code pasted below:
# Load Libraries require(OpenMx) require(statmod) # ----------------------------------------------------------------------------- # Prepare Data depData <- read.table(file='depData.txt',header=TRUE) selvars <- names(depData)[c(10:19)] # ----------------------------------------------------------------------------- # Set up function for analysis nonNormTest <- function (data,nQuadPoints=10,nFactors=1) { # Number of: items; quadrature points; maximum # of thresholds; and factors (1 only at present) nItems <- dim(data)[[2]] nthresh <- vector(mode="integer",nItems)Log in or register to post comments

yes, to get it highlighted in tm you need css

I've installed and enabled
For example the R code fragment below is now highlighted.
x <- rnorm(100, mean = 2, sd = 3)
plot(x, xlab = "index", main = "Example code")

Brilliant, thank you!
mxOption(NULL, "Number of Threads", omxDetectCores() - 1)
I really like this, although I recognize that the ~6% red-green colorblind men and the small fractions of other colorblindness groups may not view this modification with rose-colored glasses.
