No, search() shows you the packages which are currently attached, plus 
other objects that are attached (see its help page).

I am not sure what you mean by `loaded'.  Some packages have namespaces, 
and the namespace can be loaded without the package being attached.
For a list of loaded namespaces use loadedNamespaces().

Not indeed.  However, remove.packages() inside R will work for you, 
without Perl or the make tools.
