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:


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 )

options( old.op )


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:
