fit_angles {Correlplot}

Fit angles to a correlation matrix

Description

fit_angles finds a set of optimal angles for representing a particular correlation matrix by angles between vectors

Usage

fit_angles(R, ifun = "cos", ntrials = 10, verbose = FALSE)

Arguments

R

a correlation matrix.

ifun

an angle interpretation function (cosine, by default).

ntrials

number of trials for optimization routine nlminb

verbose

be silent (FALSE), or produce more output (TRUE)

Value

a vector of angles (in radians)
