Hi,
The function locator() allows me to add points by mouse on function plot()
I have draft. But the points can not be edit once I have made the click.
How can I remove or just move the points I made on the draft?
I use the locator function like this:
plot(1,1)
locator(type=o)
Thanks.

You cannot. The plotting model
Depending on the complexity of your graphic, you could also just re-draw
the entire thing every time you want to make a change.

You cannot move or edit them interactively, but you can save
the locations of those points by using:
a - locator(type=o)
# e.g. click on three locations
a
$x
[1] 0.8559376 1.1778126 1.2340626
$y
[1] 1.2256976 1.2501162 0.8402324
You could now delete or modify the points and then use lines()
The function put.points.demo in the TeachingDemos package allows you to
add points, delete points, and move points on a scatterplot (and also
computes some summaries based on the points).
It actually uses locator behind the scenes and redraws the plot each
time, but it gives the effect. If that
Maybe I have to white a function for the purpose base on loacator. Thanks
for the reply.

Thanks. I have tried put.points.demo, it helps, maybe some more modify then
it would be suitable for me. Thank you again.
