QUARTERLY {bimets}  R Documentation 
Quarterly (Dis)Aggregation
Description
This function returns a quarterly (dis)aggregated time series, using as input an annual, semiannual, monthly or daily time series.
Usage
QUARTERLY(x = NULL, fun = NULL, avoidCompliance = FALSE, ...)
Arguments
x 
Input time series that must satisfy the compliance control check defined in is.bimets .

fun 
Only for daily or monthly input time series:
STOCK: the value of the input time series in the last observation of a quarter is assigned to the same quarter of the output time series.
NSTOCK: the value of the input time series in the last nonmissing observation of a quarter is assigned to the same quarter of the output time series.
SUM: the sum of input observations in a quarter is assigned to the same quarter of the output time series.
NSUM: the sum of input nonmissing observations in a quarter is assigned to the same quarter of the output time series.
AVE: the average of input observations in a quarter is assigned to the same quarter of the output time series.
NAVE: the average of input nonmissing observations in a quarter is assigned to the same quarter of the output time series.
Only for semiannual or annual input time series:
NULL: (default) the output value of each quarterly observation is set equal to the value of the input observation the quarter belongs to (i.e. duplicated values over the period)
INTERP_END: the value of the input time series in a period is copied into the last quarter of the output time series that lies in the same period. Other values are calculated by linear interpolation.
INTERP_CENTER: the value of the input time series in a period is copied into the median quarter of the output time series that lies in the same period. Other values are calculated by linear interpolation.
INTERP_BEGIN: the value of the input time series in a period is copied into the first quarter of the output time series that lies in the same period. Other values are calculated by linear interpolation.

avoidCompliance 
If TRUE , compliance control check of input time series will be skipped. See is.bimets
