?contrast in the contrast package gives me the following description. However, I have no idea what Type II and III contrasts are. Could somebody explain it to me? And what does 'type' mean here?
*‘type’*: set ‘type="average"’ to average the individual contrasts (e.g., to obtain a Type II or III contrast) ______________________________________________ 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.
