Hello All,
?environmentName shows how to get the environment name. But I don't
see how to set the name in the first place. Could you tell me where to
look for the function that set the environment name?
It is not AFAIK possible from R code. environmentName() will give the
name which has been assigned at C level, but names(), which would
otherwise work, is disabled for non-vector objects.
The underlying reason is the unusual copying semantics of
environments -- it makes little sense to allow the name to be changed.
I do wonder why you would want this: if there is a good reason then we
could perhaps allow new.env() to set the name. But I added
environmentName() to be able programatically to identify system
environments such as packages and namespaces, especially the latter.
