In gtog/dMisc: A Collection of Helper Functions for Doing Financial Data Analysis

Description

This function returns the angle between two vectors u and v. If u and v are orthogonal then the angle will be 90 degrees. This is a helper function for dMisc::plotCovEllipse(). It can be called directly if needed.

Usage

getAngle(u, v)

Arguments

u	a vector of numeric values. (Must be at least length = 2)
v	a vector of numeric values. (Must be at least length = 2)

Details

Original code from StackOverflow, but I don't have attribution.

Value

the angle between the two vectors u and v.

Examples

u <- rnorm(5,0,1)
v <- rnorm(5,0,1.5)
