[R] power spectrum of eeg

Hi, I need to find the power spectrum of an eeg and display frequency in hz. I found two functions, spectrum or auspec but they give me frequency from 0.0 - 0.5. How do i get frequency in Hz or KHz? Also, is it possible to plot two overlapping spectra in order to compare their peaks etc? Thanks
