I have two separate questions.
The first is when I use xlab, the labels on my tic marks disappear. Is there
a way to make them reappear? Also, is there a way to make my own labels for
the tick marks?
My second question is, after I have spent a lot of time getting my plot to
look just right, I want to save it to a file, but the only way I seem to know
how to do it is to first use postscript() and then make the plot and then use
dev.off(). I keep forgetting to do this, and I am wasting so much time. Is
there a way to save the plot after I have already made it?
