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() or points() to add them to a new graph. > plot(1, 1) > lines(a, type="o") > points(a, pch=16, col="red") ------------------------------------- David L Carlson Associate Professor of Anthropology Texas A&M University College Station, TX 77840-4352 -----Original Message----- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of Daniel Guetta Sent: Friday, August 2, 2013 12:23 PM To: David Winsemius Cc: R-help@r-project.org Subject: Re: [R] could I remove or move points in locator() based on plot()? Depending on the complexity of your graphic, you could also just re-draw the entire thing every time you want to make a change.
