predict.model() and residuals.model() fit a model and extract the in-sample predictions and residuals, respectively.

Usage

# S3 method for model
predict(object, newdata = object$data, ...)

# S3 method for model
residuals(object, ...)

# S3 method for multimodel
predict(object, newdata, ...)

# S3 method for multimodel
residuals(object, ...)

Arguments

object

A model or multimodel.

newdata

newdata

...

Passed to fit.

Value

A vector if object is a “model”, a matrix if it is a “multimodel” or “cv” containing several models.

mod <- model(lm(Sepal.Length ~ .,  iris), 
             label = "lm_iris")
