angle.mapping {changepoint.geo} | R Documentation |
Calculates the principle angle of each time vector to the reference vector. Note data points are not translated in this function and error checking is not performed!
angle.mapping(X,ref.vec.value=rep(1,length(X[1,])))
X |
A matrix containing the centralized data of size n by p. |
ref.vec.value |
A vector containing the reference vector from which the principle angle will be calculated. |
This function calculates the principle angle between each time vector and the reference vector. Note the translation within geomcp
happens outside of the function.
A vector of length n is returned with the angle mapping for each time point.
