Dear,
I am using "cwt "function from Rwave package to perform Morlet wavelet
analysis.
d1<-c(1.31673209591515, -0.171333455797346, -1.67618546079420,

1.37270541339308, 0.179612250662539, 1.33781757389541)
d1<-ts(d1deltat=1,start=c(1960,1))
library(Rwave)
D1-cwt(d1,noctave=8,nvoice=1)
After I did Morlet wavelet analysis by using function "wavelet" from
dplR package.
library(dplR)
D2<-wavelet(d1,Dt=1)
But the wavelets from two tests are very different. What is the reason??
Thank you,
Irina
