scale_to_median_radius: Scale one table to the median radius of another

In krisrs1128/mvarVis: Visualize multivariate analysis results.

Description

When making a biplot, the scales of the two sets of points aren't always comparable – only the *directions* of the projections of feature variables are meaningful. This helper rescales the points in the matrix x2 to have radius comparable to the points in x1. Specifically, we rescale x2 so it's median radius is equal to the median radius of the x1 points.

Usage

scale_to_median_radius(x1, x2)

Arguments

x1	The reference matrix used to rescale x2.
x2	The matrix to rescale.

Value

x2_scaled The matrix x2 rescaled to have the same median radius as x1.
