...s defining names.class would do the job, but completion for "environment" is hard coded in utils:::specialCompletions by means of base::ls(). As result defining names.proto does not work. I tried to make "ls" generic and to do something like: environment(ls.default) <- asNamespace('utils') environment(ls) <- asNamespace('utils') environment(ls.proto) <- asNamespace('utils') That does not work either. Is there a way to make utils:::specialCompletions use my "ls" instead of "base::ls"?? I know Deepayan Sarkar is working no...

...At the loading check after installation, the classes are not found by `isClass` and `extends` when these are called in .onLoad, but are correctly found when called in .onAttach. However findClass correctly finds the class in both case, as well as isClass if it is called with the argument `where=asNamespace('<THE.PACKAGE.NAME>')`. When the package is loaded from an open R session, the behaviour is the same. in R 2.12.1: the classes are correctly found by isClass and extends when these are called in .onLoad or .onAttach, but only at installation (i.e. at the loading check after R CMD...

In the documentation the closed thing I see to an explanation of this is that ?detach says "Unloading some namespaces has undesirable side effects" Can anyone explain why unloading tseries will load zoo? I don't think this behavior is specific to tseries, it's just an example. I realize one would not usually unload something that is not loaded, but I would expect it to do

I'm confused by this: > identical(function() {}, function() {}) [1] FALSE Yet, after loading the Matrix package (which redefines det), the following is checked (in library.checkConflicts): > identical(get("det", baseenv()), get("det", asNamespace("Matrix")), ignore.environment=T) [1] TRUE I've looked at the code in identical.c and for closures it seems to compare the FORMALS and the BODY_EXPR, so why does the first example not return TRUE as surely the formals and body are identical? case CLOSXP: return(R_comput...

It's probably because the first thing that unloadNamespace does is this: ns <- asNamespace(ns, base.OK = FALSE) If you call asNamespace("tseries"), it calls getNamespace("tseries"), which has the side effect of loading that package (and its dependencies). One way to work around this is to check loadedNamespaces() before you try to unload a package. -Winston On Thu...

Hi, I'd like to list all package PkgA functions that another package PkgB use via Depends or Imports (ignoring Suggests for simplicity). As long as PkgB uses importFrom("PkgA", ...) it's just a matter of parsing the NAMESPACE file or inspecting asNamespace("PkgB")$.__NAMESPACE__.$imports. However, what can be done in case PkgB uses import("PkgA")? Is there a function/package already available for this? Thanks, Henrik
