shapes (version 1.2.8)

shapes3d: Plot 3D data

Description

Plot the landmark configurations from a 3D dataset

Usage

shapes3d(x,loop=0,type="p", color = 2, joinline=c(1:1), axes3=FALSE, rglopen=TRUE)

Value

None

Arguments

x

An array of size k x 3 x n, where k is the number of landmarks and n is the number of observations

loop

gives the number of times an animated loop through the observations is displayed (in order 1 to n). loop > 0 is suitable when a time-series of shapes is available. loop = 0 gives a plot of all the observations on the same figure.

type

Type of plot: "p" points, "dots" dots (quicker for large plots), "l" dots and lines though landmarks 1:k if `joinline' not stated

color

Colour of points (default color = 2 (red)). If a vector is given then the points are coloured in that order.

joinline

Join the numbered landmarks by lines

axes3

Logical. If TRUE then plot the axes.

rglopen

Logical. If TRUE then open a new RGL window, if FALSE then plot in current window.
