Create multiple learners at once.

Source: R/makeLearners.R

Small helper function that can save some typing when creating mutiple learner objects. Calls makeLearner multiple times internally.

makeLearners(cls, ids = NULL, type = NULL, ...)

Arguments

cls	(character) Classes of learners.
ids	(character) Id strings. Must be unique. Default is cls.
type	(character(1)) Shortcut to prepend type string to cls so one can set cls = "rpart". Default is NULL, i.e., this is not used.
...	(any) Optional named (hyper)parameters. Alternatively these can be given using the par.vals argument.

Value

[named list of [Learner]). Named by ids.

[named list of [Learner]: R:named
