Thank you very much, I'll try it. About my question on graphics with colour...
Imagine I have a function y=y(x1, x2, x3), I'd need four dimensions to graph x1, x2, x3, and y. My idea is to use the typical 3D plot adding the information of the additional fourth variable 'y to the colour of the point. What package do you recommend to do it? Any interactive plotting package? thx -- View this message in context: http://r.789695.n4.nabble.com/multivariate-graphs-averaging-on-some-vars-tp2292039p2292270.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
