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...

I've been seeing warnings when unloading packages. They can be seen with the shiny and sp packages, among others (this is on R 3.0.2). For example: > library(sp) > unloadNamespace('sp') Warning messages: 1: In FUN(X[[2L]], ...) : Created a package name, ‘2013-12-19 12:14:24’, when none found 2: In FUN(X[[2L]], ...) : Created a package name, ‘2013-12-19 12:14:24’, when none found 3: In FUN(X[[2L]], ...) : Created a package name, ‘2013-12-19 12:14:24’, when none...

If one wants to unload compiled code for a package containing a namespace, my understanding is that .onUnload() should be used, with a call to library.dynam.unload(). This is used in e.g., the stats and methods packages, but it appears to me that the compiled code is not being unloaded when the package is detached(). Am I misunderstanding something?
