makeLearners

Create multiple learners at once.

Description

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

Usage

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. If you want to set specific hyperparameters for a learner during model creation, these should go here. You can get a list of available hyperparameters using `getParamSet(<learner>)`. Alternatively hyperparameters can be given using the `par.vals` argument but `...` should be preferred!

Value

(named list of Learner). Named by ids.

Examples

makeLearners(c("rpart", "lda"), type = "classif", predict.type = "prob")
