oneway {lattice}  R Documentation 
Fits a Oneway model to univariate data grouped by a factor, the
result often being displayed using rfs
oneway(formula, data, location=mean, spread=function(x) sqrt(var(x)))
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).

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
