[R] Interrater and intrarater variability (intraclass correlationcoefficients)

[Karl Knoblick]

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

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.
