shapes3d function

Plot 3D data

Plot the landmark configurations from a 3D dataset

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

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.

Returns

None
