detachAll | R Documentation |
This uses pkgDepTopoSort
internally so that the package
dependency tree is determined, and then packages are unloaded
in the reverse order. Some packages don't unload successfully for
a variety of reasons. Several known packages that have this problem
are identified internally and not unloaded. Currently, these are
glue
, rlang
, ps
, ellipsis
, and, processx
.
detachAll(
pkgs,
dontTry = NULL,
doSort = TRUE,
verbose = getOption("Require.verbose")
)
pkgs |
A character vector of packages to detach. Will be topologically sorted
unless |
dontTry |
A character vector of packages to not try. This can be used by a user if they find a package fails in attempts to unload it, e.g., "ps" |
doSort |
If |
verbose |
Numeric or logical indicating how verbose should the function
be. If -1 or -2, then as little verbosity as possible. If 0 or FALSE,
then minimal outputs; if |
A numeric named vector, with names of the packages that were attempted.
2

it was
tried, but failed, 3
it was not loaded, so was not unloaded.
