I use cpgramcpgram function in R to produce a cumulative perodogramperiodogram of a monthly time series its. Its horizental axis is a number between 0 and 6 labeled as frequency: what does these numbers mean?, since the frequency in cumulative periodogram should be between 0 and 0.5 like these figuresthe ones shown below (upper ones) http://ars.els-cdn.com/content/image/1-s2.0-S1364815210000502-gr3.jpg?

Also, do you know how can I create cumulative periodograms like these plots? Thanks
