fitted.errors {dae} | R Documentation |

## Extract the fitted values for a fitted model

### Description

An alias for the generic function `fitted`

. When it is
available, the method `fitted.aovlist`

extracts the fitted values, which is provided
in the dae package to cover `aovlist`

objects.

### Usage

```
## S3 method for class 'errors'
fitted(object, error.term=NULL, ...)
```

### Arguments

`object` |
An |

`error.term` |
The term from the |

`...` |
Further arguments passed to or from other methods. |

### Value

A numeric vector of fitted values.

### Warning

See `fitted.aovlist`

for specific information about fitted
values when an `Error`

function is used in the call to the
`aov`

function.

### Examples

```
## set up data frame for randomized complete block design in Table 4.4 from
## Box, Hunter and Hunter (2005) Statistics for Experimenters. 2nd edn
## New York, Wiley.
RCBDPen.dat <- fac.gen(list(Blend=5, Flask=4))
RCBDPen.dat$Treat <- factor(rep(c("A","B","C","D"), times=5))
RCBDPen.dat$Yield <- c(89,88,97,94,84,77,92,79,81,87,87,
85,87,92,89,84,79,81,80,88)
## perform the analysis of variance
RCBDPen.aov <- aov(Yield ~ Blend + Treat + Error(Blend/Flask), RCBDPen.dat)
summary(RCBDPen.aov)
## three equivalent ways of extracting the fitted values
fit <- fitted.aovlist(RCBDPen.aov)
fit <- fitted(RCBDPen.aov, error.term = "Blend:Flask")
fit <- fitted.errors(RCBDPen.aov, error.term = "Blend:Flask")
```
