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)
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. |
None
