isBaseNamespace(ns)
isNamespace(ns)
namespaceExport(ns, vars)
namespaceImport(self, ..., from = NULL)
namespaceImportFrom(self, ns, vars, generics, packages,
                    from = "non-package environment")
namespaceImportClasses(self, ns, vars, from = NULL)
namespaceImportMethods(self, ns, vars, from = NULL)
packageHasNamespace(package, package.lib)
parseNamespaceFile(package, package.lib, mustExist = TRUE)
registerS3method(genname, class, method, envir = parent.frame())
registerS3methods(info, package, env)
setNamespaceInfo(ns, which, val)
.mergeExportMethods(new, ns)
.mergeImportMethods(impenv, expenv, metaname)
.knownS3Generics
loadingNamespaceInfo()
.getNamespace(name)
..getNamespace(name, where)

Arguments

ns	string or namespace environment.
base.OK	logical.
impenv	environment.
expenv	namespace environment.
vars	character vector.
generics	optional character vector.
self	namespace environment.
package	string naming the package/namespace to load.
packages	vector of package names parallel to generics.
package.lib	character vector specifying library.
mustExist	logical.
genname	character.
class	character.
envir, env	environment.
info	a 3-column character matrix.
which	character.

metaname	the methods table name.

Details

packageHasNamespace does not indicate if the package has a namespace, rather if it has a ‘NAMESPACE’ file, which base and many older packages do not. But then you are not intended to be using it ....
