Dear all, I would like to create an random time serie of POSIXct elements inside a certain range of dates and time. For example a sequences of date/time of 400 elements, randomly choosen, with all dates between 2002-12-01 and 2002-12-31 and all time between 07:00:00 and 23:00:00. Would anyone know if there is a specific R - function for that ? Many thanks in advance, Jessica _________________________________________ Jessica Gervais Tel: +352- 425991-628 Mail: jessica.gervais at tudor.lu Resource Centre for Environmental Technologies, Public Research Centre Henri Tudor, Technoport Schlassgoart, 66 rue de Luxembourg, P.O.
