[R] fft(x, inv=TRUE)

[PLauren@genelogic.com]

I started out with a real vector b and then obtained its Fourier transform
thus
B<-fft(b)
When I did
F<-fft(B, inv=TRUE)
I expected that F would be the inverse FT of B but it still has imaginary
components.

Should the inverse FT not be purely real? Am I missing something?

Thanks,
Peter.
