Hi bharat,
I think there is a conflict between your image size and resolution.
You need a lot larger height and width in pixels to get 300 dpi
resolution for the whole plot.

 tiff("test.tiff", units = "px", width = 2200, height =
1250, res = 300)

would probably do it for you. How come you can't change the width and
height in pixels?
