getNamespaceExports("base") error
Prof Brian Ripley wrote:
It would seem more logical to use x. Today it has the same contents as baseenv() (but a different enclosing env), but that may change. I do wonder why you are using this: the R code clearly doesn't. For base is not a normal namespace and is automatically imported into every other namespace (or similar words, as 'import' is used in a couple of senses in the documentation).
I came across this programmatically applying getNamespaceExports to a vector of namespaces where 'base' happend to be a member. I will use ls(.BaseNamespaceEnv, all=TRUE) instead . Thank you! Matthias

Hi!
getNamespaceExports("base")
Error in ls(NULL, all = TRUE) : using 'as.environment(NULL)' is defunct
getNamespaceExports
function (ns)
{
ns <- asNamespace(ns)
if (isBaseNamespace(ns))
ls(NULL, all = TRUE)
else ls(getNamespaceInfo(ns, "exports"), all = TRUE)
}
<environment: namespace:base>
One possible way to fix this could be to changed to e.g.
if (isBaseNamespace(ns))
ls(envir=baseenv(), all = TRUE)
Observed with
R 2.5.0 & R 2.6.0 devel (2007-05-12 r41546)
(one has to go back to R 2.3.1 to see it working)
