metric_vec_template() is useful alongside
implementing new custom metrics.
metric_summarizer() calls the metric
metric_vec_template() is a
generalized function that calls the core implementation of a metric function,
and includes a number of checks on the types, lengths, and argument inputs.
metric_vec_template( metric_impl, truth, estimate, na_rm = TRUE, cls = "numeric", estimator = NULL, ... )
The core implementation function of your custom metric. This core implementation function is generally defined inside the vector method of your metric function.
The realized vector of
A character vector of length 1 or 2 corresponding to the
The type of averaging to use. By this point, the averaging
type should be finalized, so this should be a character vector of length 1\.
By default, this character value is required to be one of:
Extra arguments to your core metric function,
metric_vec_template() is called from the vector implementation of your
metric. Also defined inside your vector implementation is a separate
function performing the core implementation of the metric function. This
core function is passed along to
