Dear all,
if I plot to a PNG, the color of filled points (pch 21:25) in legend() is ignored (i.e., only the
background color is used). It does not matter whether I specify the default
png(bg="white") or png(bg="transparent").
The example below
x <- rnorm(10)
y <- rnorm(10)
plot(x, y, pch = 21, cex = 1.5,
xlim = range(x, y) * 1.2, ylim = range(x, y)*1.2,
col = "black", bg = "lightgrey")
legend("topleft", legend = "foo", inset = 0.02,
bg = "white", pch = 21, pt.cex = 1.5,
col = "black", pt.bg = "lightgrey")
works as desired on windows(...) but fails to show the color in the legend on
png(...).
Any suggestions?
