There's no limitation of 8 (I'm not sure where you got that; ?par doesn't say that). For example, xyplot((y + g) ~ x, groups = g, data = expand.grid(x = 1:10, y = 1, g = 1:20), type = "l", lty = c("22", "42", "62", "82", "A2", "C2", "E2", "26", "46", "66", "86", "A6", "C6", "E6"), col = "black") > I know some graphics from papers containing lines with equally > distance points on the lines (one type of point per line) > as a form of distinction. Can this be realised using grouped lattice > plots with regression lines? Not directly. You will need to pre-compute the points on the lines and plot them as regular points, with type="o" to join them by lines. -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.
