Re: [R] Identify points (was Plot error)
This is exactly what I want as I will have several thousand data points on the final graph i make, so the scroll over option is ideal. I've read the TeachingDemos pdf, I'm working on a Mac so Cannot use HWidentify. I have installed and loaded the TeachingDemos package but im having trouble loading the tkrplot package after installing it won't load. library(tcltk) Loading Tcl/Tk interface ...

I have installed and loaded the TeachingDemos package but im having trouble loading the tkrplot package after installing it won't load. library(tcltk) In the Mac GUI Package Installer, I cannot even find a package by that name. However, then running the HWidentify example after require(Teaching Demos), tcltk does get loaded as well as X11, making me think you need to provide further information such as that requested in the Posting Guide.

Re: [R] Identify points (was Plot error)
You can always use the identify() function which will leave the id of the point on the plot; see ?identify. But you do eventually have to sort out your Mac problem. Sorry, I can't help with that. -Peter Ehlers On 2010-07-18 7:43, James Platt wrote: This is exactly what I want as I will have several thousand data points on the final graph i make, so the scroll over option is ideal.
