Maybe something like: k <- kernel(...) spectrum(c(rev(k$coef),k$coef))
Since the kernel is symmetric?

I tried: spectrum(kernel("daniell", 100), taper=0, log="no") but I get: Error in complete.cases(object) : not all arguments have the same length I can plot the kernel but that is only in the time-domain. I would like to see the spectrum of the kernel. Any ideas?
