I am not understanding something about generating PNG plots.
I have tried several ways to obtain something other than a transparent
background, but nothing I've done seems to change the background.
dev.print(png, width=800, height=600, bg='red', filename='example.png')
which I thought would give a red background, simply gives the same
transparent background I always get.
And I also don't understand why the default background is transparent,
when the documentation seems to say that it's white:
png(filename = "Rplot%03d.png", width = 480, height = 480,
pointsize = 12, bg = "white", res = NA,...)
(This is on a Kubuntu dapper 64-bit system.)
[I looked through the mail archives, and there seem to be a few very
old postings talking about the opposite problem, but nothing recent;
so I conclude that I'm doing something wrong.]
