eyeBall: A novel approach to visualizing random rotations.

In heike/rotations: Tools for working with rotational data

Description

This function produces a three-dimensional globe onto which the on column of the provided sample is drawn. The data are centered around a provided matrix and the user can choose to display this center or not. Based on ggplot2 package by Wickham (2009).

Usage

  eyeBall(Rs, center = id.SO3, column = 1,
    show_estimates = FALSE, xlimits = c(-1, 1),
    ylimits = c(-1, 1), ...)

Arguments

Rs	the sample of n random rotations
center	point about which to center the observations
column	integer 1 to 3 indicating which column to display
show_estimates	rather to display the four estimates of the principal direction or not
xlimits	limits for the x-axis, appropriate range is [-1,1]
ylimits	limits for the y-axis, appropriate range is [-1,1]
...	Additional arguments passed to ggplot2

Value

a ggplot2 object with the data dispalyed on a blank sphere
