spin3R

Description

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 device. 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.
