Thank you
I spend more time looking into it since I placed the question and it seems
that there is a conflict between two or more packages when open jointly with
the wavelet package for this specific example. I am trying to identify the
packages.
Many thanks againÂ

The function "align" produces an error with the present example provided in the
vignente of wavelets
# obtain the two series listed in Percival and Walden (2000), page 42
X1 <- c(.2,-.4,-.6,-.5,-.8,-.4,-.9,0,-.2,.1,-.1,.1,.7,.9,0,.3)
X2 <- c(.2,-.4,-.6,-.5,-.8,-.4,-.9,0,-.2,.1,-.1,.1,-.7,.9,0,.3)
# combine them and compute DWT
newX <- cbind(X1,X2)
wt <- dwt(newX, n.levels=3, boundary="reflection", fast=FALSE)
# align
wt.aligned <- align(wt)
Error en xy.coords(x, y) :
 el argumento "y" está ausente, sin valor por omisión
Would you happen to know if this function is not available or if there is
another way to use this function beyond what is given in the example so it
works
Thank you
