Perform fast and memory efficient timeweighted averaging of values measured over intervals into new arbitrary intervals. This package is useful in the context of data measured or represented as constant values over intervals on a onedimensional discrete axis (e.g. timeintegrated averages of a curve over defined periods). This package was written specifically to deal with air pollution data recorded or predicted as averages over sampling periods. Data in this format often needs to be shifted to nonaligned periods or averaged up to periods of longer duration (e.g. averaging data measured over sequential nonoverlapping periods to calendar years).
