The variables are unordered factors, stored as integers 1:9, where 1 means "Full-time employment" 2 means "Part-time employment" 3 means "Student" 4 means "Full-time self-employee" ... Does euclidean distances make sense on unordered factors coded as integers? ______________________________________________ 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.
