resid.errors: Extract the residuals for a fitted model In dae: Functions Useful in the Design and ANOVA of Experiments

Description

An alias for the generic function `residuals`. When it is available, the method `residuals.aovlist` extracts residuals, which is provided in the package dae to cover `aovlist` objects.

Usage

 `1` ```resid.errors(...) ```

Arguments

 `...` Arguments passed to `residuals.aovlist`.

Value

A numeric `vector` containing the residuals.

Note

See `residuals.aovlist` for specific information about the residuals when an `Error` function is used in the call to the `aov` function.
