Estimate the radius of the background circle based on the randomly generated points

Description

The space of projected bases is a circle when reduced to 2D. A radius is estimated using the largest distance from the bases in the data object to the centre point.

Usage

get_space_param(dt, ...)

Arguments

dt	a data object collected by the projection pursuit guided tour optimisation in the tourr package
...	other arguments passed to compute_pca()
