R help - Dec 2008 - overwrite title

Hi, useRs-

I have a plot with a title generated automatically. 
I need to overwrite the title, but I can't figure out how to do that. 
I've tried the following:

   title( "abc", bg='white')

But, that does not set the title background as white.
Now I am stuck and need your help. Thanks-

Lacking specifics about what you actually did, one can only guess.  
Have you yet tried setting
..., main = "" , .... within the plot call, whatever that might have  
been?

Failing that, the way to specify the color of the "main" argument to  
title() is not bg (which is an argument for the plot device), but  
rather col.main   At least that is how I read the par() help page.

plot(1:10)
title(main = "test")

#... now
title(main="test", col.main="white")

Doesn't completely white it out on my screen display.

I have played with overwriting text on charts by using 'white' text and 
various other tricks.
As David W. said, there's usually a slight ghost left behind.

My recommendation would be first and foremost to set up a miniscript to 
regenerate your plot, and change the title text to whatever you really 
want, rather than hacking the display via overwrites.

Second, you might want to draw a borderless box )with fill color equal 
to your chart background) over the existing text, then write the new title.
