R help - Apr 2003 - plots

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?

Which version of R are you using on which platform?  Which plot were you 
trying to draw that cause this?  Can you give us some reproducible 
examples?  

The example seems to work fine:

plot(1:10, xlab = "A Label", ylab = "Another Label",
     axes = FALSE)
axis(1, at = seq(1, 10, by = 2),
     labels = c("a", "b", "c", "d",
"e"))
axis(2, at = seq(1, 10, by = 2),
     labels = c("f", "g", "h", "i",
"j"))

You should be typing your R codes in a text editor (whatever platform 
you're working on).  Then copy and paste the codes into R.  This way you 
are not only able to make changes easily but also you have a good way to 
keep your history.

There are other graphics formats available, such as png(), pdf()...etc.

Once you have the plot looking just right on the screen, it is not 
necessary to replot in order to save it as a file.  Check out the 
functions dev.copy(), dev.copy2eps, and dev.print()
