Where did you get `result' from? (What program spells that badly and where does ppi come from?) Your last example gives for me (using ImageMagick) identify -format "%wx%h res: %x" Rplot001.png 1920x1920 res: 944.88 PixelsPerCentimeter which is correct. I believe it is your PNG reader that is buggy, not R.
