1	multiWayAnova_()

Options:

'SS type' type of sum of squared, default: type = 2. See Details in Anova
'Effect size' compute and prints effect size (partial eta squares)
'Summary statistics for groups' prints summary statistics for groups formed by all combinatuions of factors
'Pairwise comparisons of means' performs post-hoc Tukey's HSD test on significant (p < .05) or close to significant (p < 0.1) effects.

On OK, the following operations are carried out:

Computes ANOVA using Anova
Computes effect sizes (partial eta squared)
Prints a summary of marginal statistics (count, min, max, mean, ds)
runs post-hoc analysis on significant or close to significant effects
Generates an 'extended' dataset (extension .ext) containing additionak columns '<factorA.factorB:...>' that allows differentiate measures from groups or subjects with same factors levels. This 'extended' dataset is useful for ploting means and post-hoc analysis
