[Rd] Doc suggestion for detach (and library) (PR#1213)

[murdoch@stats.uwo.ca]

The example in ?detach says

     ## could equally well use detach("package:eda")
     ## but NOT  pkg <- "package:eda"; detach(pkg)

It would be helpful if the code to do what was meant above was given,
e.g.

     ## Instead, use

     library(eda)
     pkg <- "package:eda"
     detach(pos = match(pkg,search()))

It might also be helpful to include a "character.only" example in the
help for library.
