similar to: unloadNamespace, getPackageName and "Created a package name xxx " warning

Hi, There seems to be a problem with setGroupGeneric() from package 'methods'. The symptoms are somewhat erratic, in the sense that small changes may lead to any of the following behaviours. 1.Package works without problems on Windows and installs on Linux but gives error when loaded with library(). 2.Package installs on both systems and gives error when loaded on any of them. 3.

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

Hi, I am facing with a strange behaviour of isClass and extends when these are called in .onLoad in both R 2.12.1 and R 2.13.0. This is preventing my package from doing some object initializations at a proper place (i.e. in .onLoad). Suppose one defines two S4 classes in a package, and that one needs to check the inheritance between these two when loading the package (e.g. to validate slots

Hello, I was just reminded from a comment in some code that I had submitted this bug report last year, but it does not appear to have been addressed in R 3.5.0. Can this please be fixed, or is there a specific reason that it cannot be addressed?

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

A isNamespaceLoaded() function would be a useful thing to have in general if we are interested in readable code. An efficient implementation would be just a bonus.

isLoadedNamespace() sounds fine to me..

I'm trying to resolve a small problem that has arisen from introducing a NAMESPACE for the package SparseM. Prior to the namespace I had a class "matrix.diag.csr" that consisted of diagonal sparse matrices. It was defined to have the same attributes as the matrix.csr class and setAs was used to define how to coerce integers and vectors into this form:
