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

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.

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()

Value

a tibble object of the centre and radius of the basis space

Details

This is a wrapper function used by explore_space_pca() and should be be called directly by the user
