Dear all, I have a question regarding the 'y <- -loc[,2]' in ?cmdscale. Although I see that the plot is more sensible when using the '-loc' instead of just 'y <- loc[,2]', I don't understand if there is a statistical reason to do '-loc[,2]'. So is this just to make the graph look better, or should I always use -loc for the y-axis of a similar plot for a completely different data set.
Kind regards, Paul Lemmens ______________________________________________ R-help@stat.math.ethz.ch 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.
