You need to read the help for postscript(), which specifically tells you
in the Details section to use:

postscript(..., onefile = FALSE, horizontal = FALSE, paper = "special")

to generate EPS files.

There is no resolution setting for a postscript file per se, since PS is
a device independent vector based format and the resolution of the
output is dependent upon the target device/viewer. One exception to this
would be the embedding of a bitmapped object in a PS file, but that is
not applicable here.
