Hi all --
So I have a very simple dataset, which consists of 60 subjects,
who watched one of three videos, drank one of two drinks, and
completed a task. The response variable is the time to complete the
task. The ANOVA command is simple enough: anova(aov(time ~ drink *
video, data = df));
However, the videos were randomly selected; I need to use the
random effects model for them. So I tried anova(aov(time ~ drink +
Error(video), data = df)); This gives me a "no applicable method for
The command aov works, but doesn't give me anything I can interpret
effectively. Is there a simpler command I should be using? Am I
doing something wrong?
