Apparently highlight (is that a command of your creation or something  
else? It would help to know a little more about it) takes a file as  
argument. So the only ways to have it work on a selection are:
1- to modify highlight to accept either a file or some raw text from  
standard input (or only raw text)
2- copy the current selection to a temporary document and feed that to  
highlight

If 1, then you can use highlight with no argument and set TM to feed  
it selection or document. If the new version can only be made to  
accept raw text you can still use it independently this way:
	cat doc.r | highlight -H -...

If 2, the command would look like

	# create a temporary document (cleanly)
	tmpDoc=$(mktemp)
	# fill it with TM input (selection or doc)
	cat > $tmpDoc
	# feed it to highlight
	highlight $tmpDoc -H -...


Otherwise, depending on the purpose of these snippets, there are  
plenty of online paste boards with syntax highlighting support for R,  
and one is accessible from textmate (Paste selection online). You get  
something like this:
	http://pastie.textmate.org/private/epwkcdngtzljzkf1zxg
with a link you can embed in other pages (and I guess also in a wiki).  
I am also pretty sure I saw some that could output the html  that is  
displayed (with the colors etc.).

Hop that helps.
