| tidy_optim {broom} | R Documentation |
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.
tidy_optim(x, ...)
x |
A list returned from |
... |
Additional arguments. Not used. Needed to match generic
signature only. Cautionary note: Misspelled arguments will be
absorbed in |
A tibble::tibble with one row per parameter estimated by optim
and columns:
parameter |
name of the parameter, or |
value |
parameter value that minimizes or maximizes the output |
