(This article was first published on

**Romain Francois, Professional R Enthusiast**, and kindly contributed to R-bloggers)I pushed highlight 0.2-5 on CRAN. This release improves the latex renderer and the sweave driver so that multiple lines character strings are properly rendered.

This example vignette shows it:

\documentclass[a4paper]{report}\begin{document}<<echo=FALSE,results=hide>>= old.op<-options(prompt=" ", continue=" ")@ <<>>= require(inline)require(Rcpp)convolve<-cxxfunction(signature(a="numeric", b="numeric"), ' NumericVector xa(a); int n_xa = xa.size() ; NumericVector xb(b); int n_xb = xb.size() ; NumericVector xab(n_xa + n_xb - 1,0.0); Range r( 0, n_xb-1 ); for(int i=0; i<n_xa; i++, r++){ xab[ r ] += noNA(xa[i]) * noNA(xb) ; } return xab ; ', plugin="Rcpp")convolve(1:4, 1:5)@ <<echo=FALSE,results=hide>>= options(old.op)@\end{document}

Once processed with Sweave, e.g. :

require(highlight)driver<-HighlightWeaveLatex(boxes=TRUE)Sweave('test.Rnw', driver=driver)texi2dvi('test.tex', pdf=TRUE)

we get this result, embedded below with google viewer:
