Maybe something like:

k <- kernel(...)

Since the kernel is symmetric?

Subject: [R] Spectrum of a kernel

For purely educational purposes I would like to see the spectrum of a kernel. 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?
