Lattice is not a good tool for interactive brushing. For non-interactive grouping, you could do parallel(iris[1:4], groups = iris$Species, horizontal.axis = FALSE) parallel(iris[1:4], groups = (iris$Sepal.Width < 3), horizontal.axis = FALSE) etc. -Deepayan ______________________________________________ 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.
