Export a graph to .eps file with R

Question

How do I export a graph to an .eps format file? I typically export my graphs to a .pdf file (using the 'pdf' function), and it works quite well. However, now I have to export to .eps files.

Answer 1

The easiest way I've found to create postscripts is the following, using the setEPS() command:

setEPS()
postscript("whatever.eps")
plot(rnorm(100), main="Hey Some Data")
dev.off()

Answer 2

If you are using ggplot2 to generate a figure, then a ggsave(file="name.eps") will also work.

Answer 3

Yes, open a postscript() device with a filename ending in .eps, do your plot(s) and call dev.off().

Answer 4

The postscript() device allows creation of EPS, but only if you change some of the default values. Read ?postscript for the details.

Here is an example:

postscript("foo.eps", horizontal = FALSE, onefile = FALSE, paper = "special")
plot(1:10)
dev.off()

Answer 5

Another way is to use Cairographics-based SVG, PDF and PostScript Graphics Devices. This way you don't need to setEPS()

cairo_ps("image.eps")
plot(1, 10)
dev.off()
