Usage

meansComp(object, spec, graph=TRUE, ...)

Arguments

object

A fitted model object that is supported, such as the result of a call to LinearModel, lm or aov.

spec

A character vector specifying the names of the predictors over which means comparisons are desired. specs may also be a formula or a list (optionally named) of valid specs. Use of formulas is described in the Overview section below.

  data(senso)
  res <- LinearModel(Score~ Product + Day , data=senso, selection="none")
  meansComp(res,spec="Product")
  
if (FALSE) {
  ## or equivalently
  meansComp(res, ~Product)

  ## and with the sidak correction
  meansComp(res,~Product,adjust="sidak")
}
