I am pulling a time series using get_data, and for some ids I get multiple identical lines. What causes such behavior?
data_frame<- data.table(get_data(list("NO0003019002"), list('TR.PriceClose(SDate=19890101,EDate=20170805,Curn=NOK).date','TR.PriceClose(SDate=19890101,EDate=20170805,Curn=NOK)'),debug=F))
data_frame has 4060 lines, while unique(data_frame) has 117. Note, that it is not due to prices staying the same, as one of the columns is the time stamp.
