Dear list,
I've been trying this for a few hours and I just don't understand how lattice works with groups and subscripts.
Consider the following example,
xx <- seq(1, 10, length=100) x <- rep(xx, 4) y <- c(cos(xx), sin(xx), xx, xx^2/10) fact <- factor(rep(c("cos", "sin", "id", "square"), each=100)) fact2 <- factor(rep(c("periodic", "not periodic"), each=100)) my.df <- data.frame(x=x, y=y, fact = fact, fact2 = fact2) head(my.df) myColors <- c(2, 4) xyplot(y ~ x | fact, data = my.df, groups = fact2, panel = panel.superpose, panel.groups = function(..., group.number) { panel.xyplot(...) #panel.xyplot( ..., col=myColors[group.number]) # error })
My aim is to assign a custom color to each group, but for some reason the col parameter is already given to panel.xyplot and I can't find where it gets the values from.
Many thanks, baptiste _____________________________ Baptiste AuguiƩ School of Physics University of Exeter Stocker Road, Exeter, Devon, EX4 4QL, UK Phone: +44 1392 264187 http://newton.ex.ac.uk/research/emag ______________________________________________ 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.
