I need to export images from R for publication in a journal. I found the tiff() function for this useful. I need atleast 300 dpi images. What should be the height, width and unit be set as?
I usually use height = 10, width = 10, units = "in", res = 300 and the images produced are good for on screen visualisation but I am not sure if they are suitable for publication in A4 pages. Reducing the height and width overlaps the text in the plots.
