[R-SIG-Finance] periodogram

[babel at centrum.sk]

Hello R
I have a problem with periodogram. I cant find the suitable function for this. I would like to plot correlograms with the ACF function acf(x) and then the corresponding periodogram. But the periodograms I found in the R package GeneCycle and stats does not produce the desired output for me. I will prefer something like the Statgraphic produce (the image in appendix). Can you help me please with this beginners question?
Thank you in progress.
