Hello Peter, thanks for your quick response - you have hinted into the right direction. I triple-checked my data and - how embarrassing - I actually did have different data matrices. Due to a faulty Win Excel macro that sorted data into groups after data collection, I ended up with different data in my 3 groups in the Win "test" ... All good now :-). Thanks again!
Best wishes, Mareen ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
