Identify3d: Identify points in 3D

In p3d: Plot 3d data and fitted surfaces

Description

The function Identify3d allows you to label points interactively with the mouse: Press the right mouse button (on a two-button mouse) or the centre button (on a three-button mouse), drag a rectangle around the points to be identified, and release the button. Repeat this procedure for each point or set of "nearby" points to be identified.

To exit from point-identification mode, click the right (or centre) button in an empty region of the plot.

Usage

Identify3d(x, ...)

## Default S3 method:
Identify3d(
    x = pars$data[[pars$names['x']]],
    y = pars$data[[pars$names['y']]],
    z = pars$data[[pars$names['z']]],
    labels = rownames(.Plot3d.par$data), groups = NULL,
    col = Plot3d.par()$col, 
    adj = 0, debug = FALSE, pad = 0,
    offset = ((100/length(x))^(1/3)) * 0.02,
    ...
    )

## S3 method for class 'formula'
Identify3d(formula = attr(data, "formula"), data = sys.parent(), labels = NULL, adj = 0, ...)

Arguments

formula	"model" formula, of the form y ~ x + z.
data	data frame, for the formula method.
x	variable for horizontal axis.
y	variable for vertical axis (response).
z	variable for out-of-screen axis.
labels	text labels for the points, one for each point; in the default method defaults to the observation indices, in the formula method to the row names of the data
groups	A factor or variable dividing the observations into groups.
col	colors for the point labels.
adj	label adj value, passed to rgl.texts
debug	if TRUE, print debugging output.
pad	padding between point and label, in number of " " characters.
offset	offset to y value, passed to rgl.texts.
...	Other arguments passed down

Value

Identify3d returns the labels of the identified points
