Activity II- Read sampled_meter_data.table data- Extract Year, Day of Year, and Hour values from the timestamp into separate columns- Calculate the average timestamp and average intensity by year, day, and hour- Start a new workflow branch and calculate gaussian centered moving average of the intensity - Calculate the maximum of the intensity column for the preceding day (1440 previous records)- Plot the original, average, and maximum intensity in a line plot Activity I- Read meter_data.csv data- Combine the individual date and time values into a timestamp with the String Manipulation node- Convert the timestamp from String to Date&Time- Extract the records for January 2007 with the Date&Time-based Row Filter node CSV Reader Table Reader Data CitationLichman, M.
