R Documentation

Tidy a(n) manova object

Description

Tidy summarizes information about the components of a model. A model component might be a single term in a regression, a single hypothesis, a cluster, or a class. Exactly what tidy considers to be a model component varies cross models but is usually self-evident. If a model has several distinct types of components, you will need to specify which components to return.

Usage

## S3 method for class 'manova'
tidy(x, test = "Pillai", ...)

Arguments

x

A manova object return from stats::manova().

test

One of "Pillai" (Pillai's trace), "Wilks" (Wilk's lambda), "Hotelling-Lawley" (Hotelling-Lawley trace) or "Roy" (Roy's greatest root) indicating which test statistic should be used. Defaults to "Pillai".

...

Arguments passed on to stats::summary.manova

object: An object of class "manova" or an aov object with multiple responses.
intercept: logical. If TRUE, the intercept term is included in the table.
tol: tolerance to be used in deciding if the residuals are rank-deficient: see qr.

Value

A tibble::tibble with columns:

\item{term}{Term in design}
\item{statistic}{Approximate F statistic}
\item{num.df}{Degrees of freedom}
\item{p.value}{P-value}

Depending on which test statistic is specified, one of the following columns is also included:

\item{pillai}{Pillai's trace}
\item{wilks}{Wilk's lambda}
\item{hl}{Hotelling-Lawley trace}
\item{roy}{Roy's greatest root}

Examples


npk2 <- within(npk, foo <- rnorm(24))
m <- manova(cbind(yield, foo) ~ block + N * P * K, npk2)
tidy(m)
