calculatePhase: calculate peak phase

In raim/segmenTools: Tools for Functional Genome Exploration

calculate peak phase

Description

calculate phases via a Discrete Fourier Transformation, but starting at the first time point, such that phase 0/360 indicates peak at time 0, and phase 180 indicates peak at half of the cycle TODO: implement systematic phase error for time series that do not cover multiples of full cycles; phase error related to pi/resolution, see comments in testPhase

Usage

calculatePhase(x, cycles, degrees = TRUE)

Arguments

x	a time-series matrix with columns as time points, or a timeseries object as returned by processTimeseries
cycles	optional integer vector for the DFT components (number of cycles in the data) for which phases are to be calculated; all are returned if cycle is not specified
degrees	logical to indicate whether phases should be reported in degrees (0 - 360) or radians (0 - 2*pi)
