Specialized method for statistically processing a set of data already processed with the same statistical processing, on a different time interval. This method performs statistical processing by aggregation of shorter intervals. The output that volgrid6d object contains elements from the original volume this satisfying the conditions
Output data will have timerange of type stat_proc and p2 = step. The supported statistical processing methods (parameter stat_proc) are:
The start of processing period can be computed automatically from the input intervals as the first possible interval modulo step, or, for a better control, it can be specified explicitely by the optional argument start. Be warned that, in the final volume, the first reference time will actually be start + step, since start indicates the beginning of first processing interval, while reference time (for analysis/oservation) is the end of the interval. The purpose of the optional argument stat_proc_input is to allow processing with a certain statistical processing operator a dataset already processed with a different operator, by specifying the latter as stat_proc_input; this is useful, for example, if one wants to compute the monthly average of daily maximum temperatures; however this has to be used with care since the resulting data volume will not carry all the information about the processing which has been done, in the previous case, for example, the temperatures will simply look like monthly average temperatures.
