listLearners: Find matching learning algorithms.

Description

Returns the class names of learning algorithms which have specific characteristics, e.g. whether they supports missing values, case weights, etc.

Note that the packages of all learners are loaded during the search.

Usage

listLearners(obj = NA_character_, properties = character(0L),
  quiet = TRUE, warn.missing.packages = TRUE, create = FALSE)
## S3 method for class 'default':
listLearners(obj, properties = character(0L),
  quiet = TRUE, warn.missing.packages = TRUE, create = FALSE)
## S3 method for class 'character':
listLearners(obj, properties = character(0L),
  quiet = TRUE, warn.missing.packages = TRUE, create = FALSE)
## S3 method for class 'SupervisedTask':
listLearners(obj, properties = character(0L),
  quiet = TRUE, warn.missing.packages = TRUE, create = FALSE)

Value

[character | list of Learner]. Class names of matching learners or instantiated objects.
