Using which version R on which platform?
Most strange. The help page for "Arithmetic operators" clearly states in a
Note that "*
I solved this in two ways:
1. "**" was necessary to raise (-dummy + 1) to the power of B. "^" doesn't
work here, for some reason.
2. I needed to use "as.complex" which greatly simplified my code and
produces the correct response. (I had to revisit math that I had not used
in many years.)

The problem arises in the computation of U where (-dummy+1) turns negative
(the eighth and higher index values of "dummy"). You raise a negative number
to a non-integer power, for example, (-pi)^exp(1), which fails because you
would not be able to tell, which sign the resulting number should have.
I am trying to create a set of wavelets in frequency space--namely Cauchy
wavelets for an intensity analysis (von Tscharner, 2000). The wavelets are
defined by the following formula:
[(f/cf)^(cf*scale)]*[e^((-f/cf)+1)^(cf*scale)]
where *f *is frequency of length *n*, *cf* is center frequency (de
