Simple spin function to rotate and to inspect
a 3-dimensional cloud of points
Usage
spin3R(x, alpha = 1, delay = 0.015, na.rm=FALSE)
Arguments
x
(nx3)-matrix of points
alpha
angle between successive projections
delay
delay in seconds between two plots
na.rm
if TRUE 'NA' values are removed otherwise exchanged by mean
Details
spin3R computes two-dimensional projections
of (nx3)-matrix x and plots them
on the graphics devise. The cloud of points is rotated
step by step. The rotation is defined by a tcl/tk control
widget. spin3R requires tcl/tk package of R.
