One of my discoveries while learning the art of R, is that time has moved on since I did my basic statistics in school (although to my dismay the teaching of statistics in school appears also to have not noticed the movement.) I have seen a few references when people want to pie chart something, for the advice to be "find a better way." I've been reading some of the ash work (see package of same name and loads of papers on the web), also some interesting work on dot plots as an alternative to histograms. They make me feel that unless the data that you have in both histograms accidentally works well with the same set of bins you may not get the comparative assessment that you think you are getting.
I am beginning to form the opinion that in most cases (if not all) there are better alternatives to histograms. _________________________________________________ Tom Mulholland Senior Policy Officer WA Country Health Service 189 Royal St, East Perth, WA, 6004 Tel: (08) 9222 4062 e-mail: [EMAIL PROTECTED] The contents of this e-mail transmission are confidential an...{{dropped}} ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
