evaluating keystroke
On the question of evaluating keystrokes: I often plot subsets of data to get a sense of what I'm looking for. I generally run a for loop with the specification par(ask=TRUE) after each plot command, so that I can take time to look over the data before going on to the next plot by pressing RETURN.B Would it be possible to use readline() in such a command sequence to write a comment about each plot before going on to the next? This would certainly help me take quicker and better notes when examining data, and might even allow me to use R in a perception/classification experiment. Thanks, David S.
