Source: R/response.R
response.Rd

The response is either the class to be predicted for a classification problem (and it is a factor), or the dependent variable in a regression model (and it is numeric in that case). For unsupervised classification, response is not provided and should return NULL.

Usage

response(object, ...)

# S3 method for default
response(object, ...)

Arguments

object

an object having a response variable.

...

further parameter (depends on the method).

Value

The response variable of the training set, or NULL for unsupervised classification.
