I think that decision depends on the editorial policies of whoever 
publishes the article.   That's not the style used in the R man pages, 
though:  they use the "Rd.sty" style which displays \pkg{foo} in bold.  
Functions are entered as \code{function} which displays using \texttt 
(which is the same as \tt).
