In my package's zzz.R, I put
.Last.lib <- function(libpath) {
unloadNamespace("mypackage")
}
and I exported .Last.lib in NAMESPACE, with the intent that detaching
the package would also cause the name space to be unloaded. However, the
result of detach("package:mypackage") is then
Error: evaluation nested too deeply: infinite recursion /

With a hundred more or so of the last error. What is the correct way (if
any) to unload a name space using detach() alone ?
Thanks,
