Examples

# Convert the monthly series "uscpi" to quarterly frequency and fill in partial quarters at the start and end by repeating the closest value
seriesRequest <- CreateUnifiedTimeSeriesRequest()
setFrequency(seriesRequest, "Quarterly")
reqExp <- addSeries(seriesRequest, "uscpi")
setPartialPeriodsMethod(reqExp, "RepeatLastValue")
seriesCpi <- FetchTimeSeries(seriesRequest)[[1]]
