identify3d(x, y = NULL, z = NULL, labels = seq_along(x), n = length(x), 
	plot = TRUE, adj = c(-0.1, 0.5), tolerance = 20, 
	buttons = c("right", "middle"))

`x, y, z`	coordinates of points in a scatter plot. Alternatively, any object which defines coordinates (see `xyz.coords`) can be given as `x`, and `y` and `z` left missing.
`labels`	an optional character vector giving labels for the points. Will be coerced using `as.character`, and recycled if necessary to the length of `x`.
`n`	the maximum number of points to be identified.
`plot`	logical: if `plot` is `TRUE`, the labels are printed near the points and if `FALSE` they are omitted.
`adj`	numeric vector to use as `adj` parameter to `text3d` when plotting the labels.
`tolerance`	the maximal distance (in pixels) for the pointer to be ‘close enough’ to a point.
`buttons`	a length 1 or 2 character vector giving the buttons to use for selection and quitting.
