[R] clearing some part of a graph

[vincent.stoliaroff@sgcib.com]

Hi R lovers

2 questions:

1) I'd like to know how to clean the title, the sub title or the labels of
a graph. I know how to redefine it with the function title() but it
overwrites the previous title and do not replace it

2) How could I clear a whole plot (for example in a multiple figure
environment)

thanks for your help
vincent
