Hello:
I was able to get two graphs with white background in JPG format, but only the first graph with PNG format (as previously remarked). Curiously, I only got the first graph saved (with white background) for the PDF format. Code follows...
ANDREW
library(lattice) z <- expand.grid(A = LETTERS[1:8], B = letters[1:6]) z$x <- z$y <- rep(1, nrow(z))
png(file = "~/tmp/test%02d.png") lset(theme = col.whitebg()) xyplot(y ~ x | A * B, data = z, layout = c(4, 6)) dev.off()
jpeg(file = "~/tmp/test%02d.jpg") lset(theme = col.whitebg()) xyplot(y ~ x | A * B, data = z, layout = c(4, 6)) dev.off()
pdf(file = "~/tmp/test%02d.pdf") lset(theme = col.whitebg()) xyplot(y ~ x | A * B, data = z, layout = c(4, 6)) dev.off()
