R help - Feb 2012 - is there a command to withdraw already performed command in R?

Hi all,

Is there any command or function to withdraw
a command performed already  in R? For instance, after drawing a line in
existing plot, can I remove the line in the plot? I know I can use a way of
overlapping on the former line so that it looks like a removing the line,
but I'm wondering there is a command to retract the already performed
command.

Thanks.

I don't  think so, but it's  easy enough to rerun your previous
commands,
especially if you've saved then in a file.
