Wavelet transformation of a time series includes padding with zeros at the edges. This function determines the spectrum borders influenced by edge effects.
This code has been developed by Huidong Tian (archived R package WaveletCo
).
1 
start 
starting point in time. Default: 
dt 
time resolution, i.e. sampling resolution in the time domain, 
nc 
number of columns = number of observations = number of observation epochs; "epoch" meaning point in time 
nr 
number of rows = number of scales (Fourier periods) 
Period 
the Fourier periods (measured in time units determined by 
a list with the following elements:
x , y  :  coordinates of the cone of influence  
axis.1  :  tick levels corresponding to the time steps  
used for wavelet transformation:  
1, 1+dt, 1+2dt, ... if start = 1 

axis.2  :  tick levels corresponding to the log of Fourier periods:  
log2(Period)
