Hi,

I want to save a plot automatically as a pdf and jpg, and if I open the pdf device first and jpeg second only the jpeg file saves correctly . If I do reverse, only the pdf file saves correctly.

pdf('E:/my_graphs/test1.pdf', bg = "white") jpeg('E:/my_graphs/test1.jpg', quality = 100, bg = "white", res = 200, width = 7, height = 7, units = "in") plot(seq(1, 10), seq(1, 10))
dev.off()
dev.off()

In this case the pdf is not saved correctly and cannot be viewed by Adobe the error is "it has no pages". If the jpeg device is first open . It will save an empty page. Of course I can open one device at a time have the plot saved and close that device, and open it again and do same thing, but I think I should be able to have the plot command only once. I am working on a Windows machine, R.2.7.0.

Any suggestions will be very much appreciated.

Thanks,

Monica
