Export current plot from ggplot

As per @naught101's suggestion - for a 5x7 (inch!) pdf file which is a convenient size to be pasted into an A4 Word document, the following works well:

dev.copy2pdf(file="example.pdf", width = 7, height = 5)

Better yet, as an easily-called function with default dimensions:

dopdf <- function(filename = "dopdf.pdf", pdf.width = 7, pdf.height = 5) {
 dev.copy2pdf(file=filename, width = pdf.width, height = pdf.height)
}

While using ggplot2 would have let me save using the ggsave function, dev.copy2pdf is a good generic solution (answering my original question).

PNG or other formats

For example, to create a png file called myplot.png from a graph that is displayed by R, type

dev.copy(png,'myplot.png') dev.off()
