View source: R/miscellaneous.R

Description

Fits a One-way model to univariate data grouped by a factor, the result often being displayed using rfs

Usage

1
oneway(formula, data, location=mean, spread=function(x) sqrt(var(x)))

Arguments

formula

formula of the form y ~ x where y is the numeric response and x is the grouping factor

data

data frame in which the model is to be evaluated

location

function or numeric giving the location statistic to be used for centering the observations, e.g. median, 0 (to avoid centering).

spread

function or numeric giving the spread statistic to be used for scaling the observations, e.g. sd, 1 (to avoid scaling).

Value

A list with components

location

vector of locations for each group.

spread

vector of spreads for each group.

fitted.values

vector of locations for each observation.

residuals

residuals (y - fitted.values).

scaled.residuals

residuals scaled by spread for their group
