R help - May 2006 - Interrater and intrarater variability (intraclass correlationcoefficients)

It sounds as thought you are interested in Hoyt's Anova which is a form
of generalizability theory. This is usually estimated using by getting
the variance components from ANOVA.

Dear Harold,
 
Thanks! I searched for Hoyt's Anova in R - but without success. Do you know
if there is something available in R?

Well, depending on your design you can get the variance components from lmer or
aov. Instead of looking for Hoyt's ANOVA in R, you should look at the method
itself and then see how you can use the methods in R for estimating variance
components.
