[R] package names in Latex

As far as I know, the only difference between \it and \em is that \em 
words are unitalicized in an italics portion of the text, which is 
desirable in most cases.

However, I am not sure that italics is the most common solution, perhaps 
because it is really important for a package name to be very easy to 
read and spell even if the name is a meaningless sequence of letters, 
which is not always the case in italics. In some R manuals (such as the 
"Short Introduction to R"), package names are boldfaced. Personally, I 
tend to type them in TT font, as if they were function names. I guess 
all solutions are OK if they are used consistently throughout the document.
