Hi All,

When I teach an intro workshop on R, I've been minimizing "quote confusion" by 
always using quotes around package names in function calls. For example:

install.packages("Hmisc")
update.packages("Hmisc")
library("Hmisc")
citation("Hmisc")
search()  # displays package names in quotes
detach("packages:Hmisc")  # just as search displayed it


FWIW, the style for JSS now enforces (via Achimitization) the use of quotes as you show above.
