It is possible to embed a raster image inside eps, but AFAIK R does not do this. Other than that, your questions do not apply to eps. Rendering resolution only comes into play when you put it into a raster software (like photoshop) or print it.
Beyond that, we don't know what you are doing with the file after R generates it, and this is not a digital publishing mailing list so this isn't the right forum to continue this discussion.
