[R] repeated measures ANOVA using Anova in car library

[John Fox]

Dear Rudiger,

See the following paper in the R Journal, which, among other things, shows how to set up a repeated-measures ANOVA or MANOVA using Anova(): <http://journal.r-project.org/archive/2013-1/fox-friendly-weisberg.pdf>.

I hope this helps,
 John
