phaseplot: Phase-phase 2D or 3D plot of a time wave

Description

This function returns a 2D or 3D representation of a time wave according to its first, second and possibly third derivatives.

Usage

phaseplot(wave, f, dim = 3, plot = TRUE, type = "l", xlab = "1st derivative", ylab = "2nd derivative", zlab = "3rd derivative", ...)

Value

• If plot is FALSE then a 2 or 3 column matrix is returned. The position of the column is related to the order of the derivative (i. e. first colum = first derivative.
