getBMRTuneResults: Extract the tuning results from a benchmark result.
In shuodata/mlr-master: Machine Learning in R

Description Usage Arguments Value See Also

Returns a nested list of TuneResults. The first level of nesting is by data set, the second by learner, the third for the benchmark resampling iterations. If as.df is TRUE, a data frame with the “task.id”, “learner.id”, the resample iteration, the parameter values and the performances is returned.

1 2	getBMRTuneResults(bmr, task.ids = NULL, learner.ids = NULL, as.df = FALSE, drop = FALSE)

`bmr`	[`BenchmarkResult`] Benchmark result.
`task.ids`	[`character(1)`] Restrict result to certain tasks. Default is all.
`learner.ids`	[`character(1)`] Restrict result to certain learners. Default is all.
`as.df`	[`character(1)`] Return one data.frame as result - or a list of lists of objects?. Default is `FALSE`.
`drop`	[`logical(1)`] If drop is `FALSE` (the default), a nested list with the following structure is returned: `res[task.ids][learner.ids]`. If drop is set to `TRUE`, it is checked if the list structure can be simplified. If only one learner was passed, a list with entries for each task is returned. If only one task was passed, the entries are named after the corresponding learner. For an experiment with both one task and learner, the whole list structure is removed. Note that the name of the task/learner will be dropped from the return object.
