[R] Lattice bwplot: Adding mean with panel.points fails in vertical arrangement

Dear collegues, given a structure of data like this: ## Data ### set.seed(100) a <- rnorm(60,10,3) s <- c(rep("A",20),rep("B",20),rep("C",20)) p <- c(rep("d",6),rep("e",6),rep("f",6),rep("g",6),rep("h",6)) df <- data.frame(a,s,p) i would like to draw a lattice bwplot

[R] ggplot2: Controlling line width of panel borders

Dear R-users, i encountered some problems when trying to adjust the line width of the axes and stripes in a plot created with ggplot2. I use the "barley" dataset of the lattice package to illustrate my problem: library(ggplot2) library(lattice) barley[["SD"]] <- 5 limits <- aes(ymax=barley$yie
