Broom tidies a number of lists that are effectively S3
objects without a class attribute. For example, stats::optim()
,
svd()
and akima::interp()
produce consistent output, but because
they do not have a class attribute, they cannot be handled by S3 dispatch.
These functions look at the elements of a list and determine if there is
an appropriate tidying method to apply to the list. Those tidiers are
themselves are implemented as functions of the form tidy_<function>
or glance_<function>
and are not exported (but they are documented!).
If no appropriate tidying method is found, throws an error.
glance_optim(x, ...)
A list returned from stats::optim()
.
Additional arguments. Not used. Needed to match generic
signature only. Cautionary note: Misspelled arguments will be
absorbed in ...
, where they will be ignored. If the misspelled
argument has a default value, the default value will be used.
For example, if you pass conf.lvel = 0.9
, all computation will
proceed using conf.level = 0.95
. Additionally, if you pass
newdata = my_tibble
to an augment()
method that does not
accept a newdata
argument, it will use the default value for
the data
argument.
A one-row tibble::tibble with columns:
minimized or maximized output value
number of calls to fn
number of calls to gr
convergence code representing the error state
