If you are willing to use grid you can set the color of the tick marks, labels and place a box around the chart like this:
x <- 1:10 y <- x*x # create box around plot library(ggplot) qplot(x, y) # black border around plot grid.edit("grill-border", height = unit(.99, "npc"), width = unit(.99, "npc"), gp = gpar(col = "black")) # black tick marks and labels grid.edit("yaxis1", gp = gpar(col = "black")) If you play around with str(grid.get("grill-border")) and the other names on this list: "plot-surrounds" "background" "plot" "grid1-1" "grill-background" "grill-vertical" "grill-horizontal" "grill-border" "xaxis1" "axis-ticks" "axis-labels" "yaxis1" "border1-1" "border" "ylabel" "xlabel" "title" and use grid.edit to make changes as in the examples above you can change quite a bit.
