or simply
ns <- getNamespace("MASS") ; unloadNamespace(ns)
yes, indeed.
The following used to work in R 3.2.5 but not in 3.3.0:
library(MASS)
ns <-.getNamespace("MASS")
unloadNamespace(ns)
Calling unloadNamespace("MASS") directly still works.

Given the extremely simple package at
https://github.com/jimhester/testUnload, which includes only one S3 method
'print.object' the following code produces a lazy load error from a new R
session (R-devel r69801)

Thanks Winston. That seems like a workaround that might be usefully
included into unloadNamespace.

In the version of R I had trivially available, the flushSession function
from switchr seems to perform as expected when tseries is loaded.

‘tseries’ is a package for time series analysis and computational
finance.
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 chec
Paul,
My switchr package (https://github.com/gmbecker/switchr) has the
flushSession function which does what you want and seems to work (on my
test machine at least).
I havent tested it under a recent Rdevel, or with that specific package,
however I will soon, as the overarching model of switchr
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

This was previously reported and fixed. See the NEWS file and bug
report 15481.

Well, yes, from the clean unloading of compiled code to the clean

Though, I also confirmed that the former is possible on a cooperative

This was rather a large shift of subject, so I've pruned the
recipients list.
Is lazy loading involved? If so I have an idea that may or may not be
relevant. We do cache in memory the lazy-loading database for speed
on slow (network-mounted or USB drive) file systems. Now the cache is

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
