getMetricSD: Extract the standard deviation from resamples for an accuracy metric from a model object.

Description

Extract the standard deviation from resamples for an accuracy metric from a model object.

Usage

getMetricSD(x, metric, which = c("all", "best"))

Arguments

x
an object with model performanc metrics
metric
a character, either "RMSE" or "AUC" indicating which metric to extract
which
a character, either "all" or "best", default is best, see details

Value

  • A numeric for the standard deviation of the selected metric across tuning parameters and resamples in the original object.

Details

Which allows the user to select whether to generate a standard deviation for the performance metric across all values of the tuning parameters and resamples, or only for resamples under the best tuning parameter. Missing values are ignored.
