Set Container Package Options
container_options(..., .reset = FALSE)
getContainerOption(x, default = NULL)
any options can be defined, using name = value.
logical
if TRUE
, the options are reset to their default and
returned.
a character string holding an option name.
if the specified option is not set in the options list, this value is returned.
container_options()
returns a list of all set options sorted by name.
container_options(name)
, a list of length one containing the set value,
or NULL
if it is unset. Can also be multiple names (see Examples).
container_options(key = value)
sets the option with name key
to value
and returns the previous options invisibly.
compare
(default = all.equal
)
useDots
(default = TRUE
) whether to abbreviate long container
elements with ...
when exceeding vec.len
(see below). If FALSE
, they
are abbreviated as <<type(length)>>
.
vec.len
(default = 4) the length limit at which container vectors are
abbreviated.
