You did not create an EPS file. See ?postscript and pay attention to the fourth paragraph under Details:

The postscript produced for a single R plot is EPS (Encapsulated PostScript) compatible, and can be included into other documents, e.g., into LaTeX, using \includegraphics{<filename>}. For use in this way you will probably want to use setEPS() to set the defaults as horizontal = FALSE, onefile = FALSE, paper = "special". Note that the bounding box is for the device region: if you find the white space around the plot region excessive, reduce the margins of the figure region viapar(mar=).
