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 again
Barnaby

    	Hi,
I couldn't reproduce the error.

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 &lt;- c(.2,-.4,-.6,-.5,-.8,-.4,-.9,0,-.2,.1,-.1,.1,.7,.9,0,.3)
X2 &lt;- c(.2,-.4,-.6,-.5,-.8,-.4,-.9,0,-.2,.1,-.1,.1,-.7,.9,0,.3)
# combine them and compute DWT
newX &lt;- cbind(X1,X2)
wt &lt;- dwt(newX, n.levels=3, boundary="reflection", fast=FALSE)
# align
wt.aligned &lt;- 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
