anova_out {schoRsch}

Format ANOVA Output

Description

Distilles the most relevant data from an output object of ezANOVA and displays the results in a compact format.

Usage

anova_out(ezout, print = TRUE, sph.cor = "GG", mau.p = 0.05,
          etasq = "partial", dfsep = ", ", corr.df = FALSE, show.eps = 0)

Arguments

ezout

Output object created by a call to ezANOVA. This call has to have included a detailed output (detailed=TRUE).

print

Force results to be displayed, even if the function output is assigned to a variable (e.g., output <- anova_out(...); logical; default=TRUE).

sph.cor

Correction method (one of "no","GG","HF"; default="GG").

mau.p

Threshold for Mauchly's test of sphericity (numerical; default=0.05).

etasq

Effect size estimate to be used; either partial eta-squared ("partial"; default) or generalized eta-squared ("generalized").

dfsep

String that delimits the degrees of freedom of each F-value (default=", ").

corr.df

Display corrected degrees of freedom when Mauchly's test of sphericity is significant (default=FALSE).

show.eps

Show epsilon estimates when Mauchly's test of sphericity is significant? 0 = do not show, 1 = print after denominator dfs, 2 = print after F-value, 3 = print after effect size (default=0).

Details

The output of a call to ezANOVA is formatted according to the guidelines of the APA (American Psychological Association) as well as the DGPs ("Deutsche Gesellschaft fuer Psychologie"; German Psychological Society).

For repeated-measures ANOVAs, sphericity corrections are automatically applied to the p-values of effects that produced a significant result in Mauchly's test of sphericity. The corresponding input arguments (sph.cor and mau.p) do not affect between-subject designs.

Value

anoout(ezout,...) returns a list containing (1) the ANOVA table, (2) sphericity tests and corrections (if applicable), (3) formatted ANOVA results, (4) notes about which correction was applied to which effect.
