Just out of curiosity (and I hope that my question does not confuse those who intuitively understood the par(new=TRUE) statement right in the beginning):
I would like to know whether beginners (learning R) had the same difficulty as I had: Intuitively I thought that par(new=TRUE) would draw a new plot (and not into an already existing plot) and that par(new=FALSE) would not draw a new plot but draw into an already existing plot - opposed to what the par(new=TRUE) statement actually does. (It would be interesting to receive an answer also from those who meanwhile reached an expert status in working with the R syntax). Perhaps my confusion is due to the fact that I am a trained right-handed that really is a left-handed (those people tend to mistake contrasts).
If there are a lot of people having this difficulty, I would like to know why the decision was made to define the mode of action of the par(new=TRUE) statement as it is now. Perhaps that helps me to understand better the way programmers tend to think.
This has been defined ages ago in the blue book (maybe in the brown one, I don't have it handy), so no chance to redefine. It confuses several users, but ?par has the nice explaination:
'new: logical, defaulting to FALSE. If set to TRUE, the next high-level plotting command (actually plot.new) should not clean the frame before drawing “as if it was on a new device”.'
