[R-sig-ME] [R] mixed model ANCOVA

[Ian Danilevicz]

Hy,
I have read a post about mixed models (the link is below) and I still in
doubt.

https://stat.ethz.ch/pipermail/r-help/2013-December/364091.html

the problem was:

>* * 1 subject factor (random, between subjects) called Subject
*>* * 3 categorical within subjects factors called Emotion, Sex, Race
*>

* * 1 continuous covariate (**WITHIN subjects**) called Score*



*the suggested models were:*ModelRT <- lmer(logRT ~ Race*Sex*Emotion +
(1 | Subject))

or using lme from the nlme package:

ModelRT <- lme(logRT~Race*Sex*Emotion, random=~1|Subject)


However, where is the Score variable?

Best Regards, Ian
