Hello, My name is Matthias and I do look for syntax regarding hierarchal anova models in R. How can I express that a factor is nested within the combination of two other factors A(B,C), e.g. for aov(...)? I did not find the corresponding expression. Furthermore, I wanted to ask whether block factors have to be specified in a specific way or are they just treated as other factors (with no interactions). Furthermore, in general an overview might be useful for beginners that describes the structural equations of more complicated anova-designs (hierarchical and block factor designs...) in the syntax of R. Best wishes and thanks, Matthias
Hi Matthias Under the main menu try help > manuals > An Introduction to R and read the section Statistical Model in R. This contains a very good general background on model syntax in R. Also try ?aov to see the use of the error argument within an ANOVA model for using multiple error strata. I hope that this helps Francisco>From: "Matthias Unterhuber" <MatUnt at gmx.de> >To: r-help at stat.math.ethz.ch >Subject: [R] multiple hierarchical anova models >Date: Mon, 12 Jul 2004 16:34:51 +0200 (MEST) > >Hello, > >My name is Matthias and I do look for syntax regarding hierarchal anova >models in R.

Hi I can recommend you two files a) http://www.psych.upenn.edu/~baron/rpsych/rpsych.html b) http://www.pallier.org/ressources/stats_with_R/stats_with_R.pdf (in french) cheers let me know whether this helped you cheers christoph Matthias Unterhuber wrote:> Hello, > > My name is Matthias and I do look for syntax regarding hierarchal anova > models in R.
