David, ?panel.abline does not indicate that 'from/to' are arguments to that function. If you read the help page carefully, you'll see that 'from/to' apply to panel.curve(). Perhaps you thought that the '...' argument can take 'from/to'; again the help page makes it clear that those are to be *graphical* parameters.
One quick fix would be to use panel.curve with, e.g. expr set to a + b*x: panel.curve(2 + .5*x, ...) Peter Ehlers Afshartous, David wrote:
All, I'm trying to truncate some lines that are added to an xyplot via panel.abline to allow additional space for inserted text. According to ?panel.abline it seems like "from" and "to" will do the trick but it does not work for the sample code below. Any hints much appreciated. Cheers, David x = seq(1,8) y.1 = .6*x + 3.5 + rnorm(8, 0, .5); y.2 = .4*x + 1 + rnorm(8,0, .5) data.ex = data.frame( x.var = c(x,x), y.var = c(y.1, y.2), id = c(rep("y1", 8), rep("y2", 8))) xyplot( y.var ~ x.var, data = data.ex, groups = id, pch = 16, panel = function(...) { panel.abline(a = 2, b = .5, lty = 1, from = 1, to = 8) panel.abline(a = 3.5, b = .6, lty = 3, from = 1, to = 8) panel.abline(a = 1, b = .4, lty = 4, from = 1, to = 8) panel.xyplot(...) }, scales = list(y = list(limits = c(0,10)), x = list(limits = c(0,12)) ))______________________________________________ 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.
