Processes data from (Actigraph) accelerometers and classifies each epoch as either bedrest or active. The output contains an additional (compared to input) "Bedrest" column. The column has a return of "a" for activity or "br" for bedrest in each line (i.e. epoch). An additional option allows for a nap ("n") classification. The "n" differs from "br" only in how long the bedrest period is. The cutoff is specifiable, see below. The function is designed to be used after wearingMarking function in the Physical Activity package.
