There are 5 features and the last one is a huge sensor data in one cell in square brackets and separated with commas. I would like to take mean, mode, sd.. etc. of this sensor data but I don't know how to remove it from brackets and analyze it. I try the modify it as String but the data is huge and the processing time is long! Is there any easier way?
