Hi Ian, Not 100% sure on this, but I've recently been wrestling with producing plots in R and I think I know the answer to your question. As far as I could tell, all the parameters for graphics are stored using par(). There is a parameter $bg, which for me is set to "transparent", but I'll bet that for you it's set to "charcoal" or something like that :-) I would not be surprised if you could set the background of your plot to transparent with the following command: par$bg <- "transparent" HTH, Jonck
This may be a dumb question, but I've wasted several hours trying to find an answer.... When I do a plot with no parameters set eg: ' >plot(d1)' it comes up with a dark gray background and blue data points. I can modify the data points using '>plot(d1, col = "red")', but I have not been able to modify the background color. '>plot(d1, bg = "white")' does not work. Any help would be most appreciated. Cheers, Ian.
