[R] discrepancy between periodogram implementations ? per and spec.pgram

explanation for this ? Is the one from spec.pgram the better one as suggested in the documentation of per {longmemo}? Finally how are these related to an estimate of the spectral density obtained from spec.arima ? Many thanks for help and clarification. Lieven Desmet Disclaimer: http
