fitted.aovlist: Extract the fitted values for a fitted model from an aovlist object

Description

Extracts the fitted values as the sum of the effects for all the fitted terms in the model, stopping at error.term if this is specified. It is a method for the generic function fitted.

Usage

# S3 method for aovlist
fitted(object, error.term=NULL, ...)

Arguments

object

An aovlist object created from a call to aov.

error.term

The term from the Error function down to which effects are extracted for adding to the fitted values. The order of terms is as given in the ANOVA table. If error.term is NULL effects are extracted from all Error terms.

...

Further arguments passed to or from other methods.

Value

A numeric vector of fitted values.

Run this code
# NOT RUN {
## 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)

## two equivalent ways of extracting the fitted values
fit  <- fitted.aovlist(RCBDPen.aov)
fit <- fitted(RCBDPen.aov, error.term = "Blend:Flask")
