ezANOVA - Within Subjects ANCOVA - printing ANOVA results without including covariates

[King10228713]

Hi, I am hoping you can give me some direction!

I am trying to run a one-way within-subjects ANCOVA using ezANOVA using the code below.

ezANOVA(myData, AATTotal, wid = ID, within = Time, within_covariates = .(ZEducationYears, ZAge, ZInstructComp), return_aov = TRUE)

The results that are returned are for the ANOVA not including the covariates. I have tested using just one covariate and using different printing methods without luck. Any guidance would be much appreciated!

With thanks,
Rachel

Based on my understanding, ezANOVA deals with covariates by first regressing out the covariates and using the residuals for ANOVA. So there would be no ouput for the covariates.
