candiscList

Canonical discriminant analyses

Description

candiscList performs a generalized canonical discriminant analysis for all terms in a multivariate linear model (i.e., an mlm object), computing canonical scores and vectors.

Usage

candiscList(mod, ...)

## S3 method for class 'mlm'
candiscList(mod, type = "2", manova, ndim, ...)

## S3 method for class 'candiscList'
plot(x, term, ask = interactive(), graphics = TRUE, ...)

## S3 method for class 'candiscList'
print(x, ...)

## S3 method for class 'candiscList'
summary(object, ...)

Arguments

`mod`	An mlm object, such as computed by lm() with a multivariate response
`type`	type of test for the model `term`, one of: "II", "III", "2", or "3"
`manova`	the `Anova.mlm` object corresponding to `mod`. Normally, this is computed internally by `Anova(mod)`
`ndim`	Number of dimensions to store in the `means`, `structure`, `scores` and `coeffs.*` components. The default is the rank of the H matrix for the hypothesis term.
`object, x`	A candiscList object
`term`	The name of one term to be plotted for the `plot` method. If not specified, one candisc plot is produced for each term in the `mlm` object.
`ask`	If `TRUE` (the default, when running interactively), a menu of terms is presented; if ask is FALSE, canonical plots for all terms are produced.
`graphics`	if `TRUE` (the default, when running interactively), then the menu of terms to plot is presented in a dialog box rather than as a text menu.
`...`	arguments to be passed down.

Value

An object of class candiscList which is a list of candisc objects for the terms in the mlm.

Examples

grass.mod <- lm(cbind(N1,N9,N27,N81,N243) ~ Block + Species, data=Grass)

grass.canL <-candiscList(grass.mod)
names(grass.canL)
names(grass.canL$Species)

## Not run: 
print(grass.canL)

## End(Not run)
plot(grass.canL, type="n", ask=FALSE)
heplot(grass.canL$Species, scale=6)
heplot(grass.canL$Block, scale=2)
