Re: [R] selecting points on 3D scatterplots
Dear list members, I was out of town when this message arrived and so didn't respond at the time. I did respond to a private email from the poster. Yes, the scatter3d() function in the Rcmdr package can identify points in 3D scatterplots drawn with rgl via the identify3d() function in the same package. Points are identified by right-clicking and dragging. The nice() function is in the car package, one of the suggested packages for the Rcmdr package. John -- original message -- It looks like Rcmdr may be able to select points on 3D scatterplots however when I try to use it's 3dscatter plot function I get the error message: could not find function nice If I copy the code: scatter3d(data$X, data$Z, data$Y, surface=FALSE, residuals=TRUE, bg=white, + axis.scales=TRUE, grid=TRUE, ellipsoid=FALSE, xlab=X, ylab=Z, zlab=Y) into the R console I get the same error message. Sorry I'm new - does anyone know where this missing nice function can be found? I tried using scatterplot3d but it doesn't rotate or zoom - which I need to be able to do to select the data... but thanks for the suggestion! . . . -- John Fox, Professor Department of Sociology McMaster University Hamilton, Ontario, Canada web: socserv.mcmaster.ca/jfox __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] selecting points on 3D scatterplots
Hello Everyone, I am new to R and need some help. I have a matrix of x,y,z coordinates that I would like to interactively plot in 3D and then using the cursor select points on the plot and have the coordinates sent to a matrix. I am using the rgl package to plot the data at the moment because it allows me to rotate and zoom. I also tried cloud and scatterplot3D. I am looking for a function like 'locator' which is used to select points on 2D scatterplots. Thanks in advance!

You could write a locator3d function using the rgl.setMouseCallbacks, rgl.user2window and rgl.window2user functions, if you can figure out how to indicate depth with a mouse click. identify3d might be a little easier.

Re: [R] selecting points on 3D scatterplots
Or with scatterplot3d: The regular identify() usage with the iris data: s3d - scatterplot3d(iris[,1:3], color=as.numeric(iris[,5])) identify(s3d$xyz.convert(iris[,1:3])) or for locator: the values you get are the 2D representation of the current coordinate system and you can use locator directly for putting text in such as in: text(locator(1), The iris data) If you want to convert back to 3D: This is not possible, because there is a while line behind that point you are clicking on Best, Uwe Ligges Duncan Murdoch wrote: On 5/12/2009 3:08 PM, Abby Drake wrote: Hello Everyone, I am new to R and need some help.

Re: [R] selecting points on 3D scatterplots
rgl will rotate and zoom, but I don't know if you can select points.
