Please respond via email to the client's needs stated below.
NOTE: You can check the resolution on your graphic by zooming in on it.
If it turns very blocky or pixelated when you zoom in, you will need higher resolution.

Hi, I've created a png graphic for a journal submission, but it is not at a high enough resolution. How can I create a higher resolution graphic in R? My preference is to save the graphic in vector format, but a high resolution raster format could potentially work too.

I've attached the data file and my R script.

Thanks, Kate ----------------------------------------------------------------------------------------------------------------------
