With a lot of data, they tend to be a spaghetti mess. They're more useful when you can brush over data to highlight it dynamically, which could show you common patterns. (E.g. that cars with smaller engines tend to have better mileage, but poorer acceleration.) At least that's my limited experience with them. Wikipedia has a page: http://en.wikipedia.org/wiki/Parallel_coordinates and the sample graph they have at the top of the page shows data that clusters on the first 5 features/dimensions, and then goes spaghetti on you. (As the article says, ordering of the dimensions is important, and they obviously got a reasonable order... or had boring data.) -- View this message in context: http://www.nabble.com/ggplot2-and-lattice-tp19579003p21036174.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.
