grid.newpage() does not work with cairo_pdf

[markconnolly]

When writing multiple pages to a cairo_pdf device and paginating with grid.newpage() only the last page is retained in the pdf file. Workaround: use the pdf device (some functionality may be lost).

require("ggplot2")
x<-1:10
y<-x^2
df<-data.frame(x,y)

cairo_pdf("cairo_pdf.pdf", width=5, height=5)
ggplot(df) + aes(x,y) + geom_point() + opts(title="plot 1")
grid.newpage()
ggplot(df) + aes(x,y) + geom_point() + opts(title="plot 2")
grid.newpage()
ggplot(df) + aes(x,y) + geom_point() + opts(title="plot 3")
dev.off()

pdf("pdf_pdf.pdf", width=5, height=5)
ggplot(df) + aes(x,y) + geom_point() + opts(title="plot 1")
grid.newpage()
ggplot(df) + aes(x,y) + geom_point() + opts(title="plot 2")
grid.newpage()
ggplot(df) + aes(x,y) + geom_point() + opts(title="plot 3")
dev.off()

Hi Mark,

This isn't a ggplot2 bug. I'd recommend sending to r-devel since it seems like a bug with cairo_pdf

Sorry about that! For some reason I was thinking grid was part of ggplot2. Maybe another step in your reproducibility process;-)
