Answer 1

If you would like an image file instead of a pdf, also the following works

ggsave(filename="myPlot.jpg", plot=last_plot())

or with additional parameters, as follows.

ggsave(filename="myPlot.jpg", plot=lastplot(),
       width = 10, height = 5, 
       units = "cm", # other options are "in", "cm", "mm" 
       dpi = 200
       )

Also following file types are supported "eps", "ps", "tex" (pictex), "pdf", "jpeg", "tiff", "png", "bmp", "svg" or "wmf".
